Right👍
Right ❤❤❤
Cbse guidence miss you 😢😢😢😢😢😢
Yes 😊😢
finally found a perfect chennel other teachers waste a lot of time in other things glad that you are explaining everthing line by line and on point thanks for uploading such content.
Welcome🎉
Nothing is more precise and significant than understanding NCERT chapters line by line. I'm deeply grateful for your videos✨ they may be free, but their impact is infinite, despite the uncertain availability of such resources.
🙌🏼I’ve struggled with this, but now I’m understanding it line by line. There are no fears left, and it’s helping me confidently explore this field with precision and progress☄️
🙏🏼It's a kind request to create videos for more chapters of Class 11th and 12th PCB,PCM as there's a significant need for them.
💪🏼Your work embodies the deepest kindness and provides immense help to students lyk me!⭐
🙏🏼Thank you for your dedication and support sir🙌🏼
Thank you for your valuable feedback 😊
@@cbseworldz 🙏🏼It's a kind request to create videos for more chapters of Class 11th +12th PHYSICS AND CHEMISTRY ATLEAST as there's a significant need for them😊
I'll try my best👍
By the way Physics is my teaching subject. So i can't promise for chemistry videos
🙌🏼Go ahead with Physics🔥 it's valuable for precise exploration✨☄️
3:05:38 sir I wish I could pay at least minimum amount for your efforts but In my home my parents wont allow online transactions. but I am sure that you will overcome your tough conditions and help us through our academics by doing these lectures. keep up the good work sir. Thanks a lot❤
Sir your language is so easy,its easy to understand 🎉
finally a true genius who focuses on understanding rather than rattafication . Sir i genuinely respect you now 🙏
Thanks for the complement 😊
4:00:33 π=C/D = [L]\[L] so dimensions get cancelled and it is dimension less quantity
Thankyou so much sir I understood everything by your videos instead of PW or vedantu. U covered the ncert book which is very good for us thankyou so much sir. U are a very good teacher.😇😇😇😇😇😇😇😇😇😇😇😇😇😇😇😇.
Welcome🎉
sir you teaching is really, really, reallyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy good. You care about the "understanding: of the students instead of just caring about what we need to just mug up without knowing the concept for the exams...your really good at explaining and teaching sir..some teachers dont have the patience to give examples and explain it in such a elaborate way for each and every concept..but you on the other hand, spend time for all the little little concepts which makes us confident and crystal clear in the concept, thanks you so much for you effort and hardwork for our studies....thanks a lot...no words can describe how much im thankful to have found you... 🥺🥺✨✨
Thanks a lot for your kind words. It means a lot 🤗
@@cbseworldz 😊
What a explanation..hats off to you sir 🙌
Every topic is crystal clear..
🙏
Thank you sir bottom of my heart because sir you cover Ncert book in limited time period. Sir I understand all the topics of chap 2. You are great sir.❤❤❤
You are most welcome🎉
🎉
M a pw student ..n still learning frm here🛐❤u r a lifesaver bruh!
👍
Best teacher in the world 🎉.. I understand everyone very fluently.. Like I don't even have to repeat any of the parts it's just seems like a piece of paper.. All thanks to sir 🎉🎉
Thanks for the complement😊
And You are most Welcome🎉
56:48 sir as this depends on the least count of the measuring instrument, how can we tell which digits are uncertain without knowing what the least count actually is?
After CBSE guidance I found this channel who teaches the whole NCERT book line by line in very easy way thank you so much sir for your hard work and efforts 🙏🏻
really sir I enjoyed your lecture. I completed this chapter in 11days. I clicked on this video for fun but later my interest build up and slowly slowly I complete this chapter I had not made efforts to study it because I have recently done with my class 10th board exam
😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊thank you sir ,well explained
Welcome🎉
Iss chanal ko share kro kuinki ye sab se achi channel hai
Thank you sir for your explanation 😊
Your explanation is better than other TH-cam teachers..
Thanks for the complement🙏
Finally i found chennal lile CBSE GUIDANCE.
Us bro😭😭😭😭
Ek number Jo kahi nahi samjha school Mai. Bhi nahi woh yaha sir apko toh bada sir hona chahiye . Love you ❤
Excellent explanation👍 but when I started solving ncert questions there is a question realated to parallax I don't know what it is. May it is a deleted topic. If yes than why there is a question related to that topic please reply🙏
It is a deleted topic. And yes some questions are there from deleted topics as well but the need not to be solved
@@cbseworldz thanks
sir is this enough for neet? Are deleted topics still there in neet syllabus?
Thank you ♥️
Ky neet k liye yeh video enough h ??
Keep it up sir
thank you so much : May God Bless you with everything you deserve and want in life
Sir, in some physical quantity, Mass and time are not use (like.. volume).But,in case of dimesional equation or formula, they are use like..[M⁰] [L³] [T⁰].Why?
Please answer
Mass length time ko generally show kiya jata hai. Inme se jo na present ho uski power zero rakh di jati hai. Ye ek standard format hai likhne ka
Thank you so much sir😊
Sir, chemistry [class 11] ka video mil skta hee?🥺.
Chemistry video not uploaded
Sir, I want to know whether the chapters and topics of Physics of Bihar Board and CBSE Board are the same or not for class 11 because I have studied from 10th CBSE but now I have taken Bihar Board.And in that too I have taken English medium, so are the topics and chapters of both the boards same or not?
Sorry. I have no idea of bihar board. You can check the syllabus of bihar board
This is the best channel bcz it explains ncert line by line😮
Sir can you please explain the rest of the chapters, from chapter 5 onwards there are no lecture of yours Sir... please it will be very grateful 🙏
I started liking physics because of you so please continue Sir.
Complete this series.
Your teaching is really good ❤
I wanted to but without enough views I can't. I also launched a chapterwise paid course at very low price but only 2 students purchased it. So I'm very sorry.
@cbseworldz can you tell sir from where to get paid chapterwise course and how much is it.
If I can afford I'll try to get it
Ch1 & 2 are free
Ch3 (part-1 to 8 already available free) for remaining part 9,10 & 11 ₹49
And what about rest of the chapters
Ch3 pe positive response nahi mila to ch4 start nahi kiye. An Next session me dekhenge
Sir please explain the definitions of all fundamental quantities as soon as possible
Best explaination 👍❤
Wow, today i found best video 💕😊
Ever forever best video of physics thanks so much sir jie . I find a lot physics reading but now i find it best teacher nd well explained

Sir aap bhut acha padhate ho ... Thank you so much because you tube per 11th ncert book se line by line reading ki sirf aapki hi video achi h ... And aise hi agle chapters ki bhi videos bna dijiye....
Welcome🎉
Chapter 3 ki video already uploaded hai
Ok sir ji thanks.. but uske kitne sare parts h 😢😢

Ok sir ji👍👍 thanks you so much🙏🙏🙏🙏🙏🙏😊😊😊😊🌟🌟🌟🌟🤗🤗🤗🤩🤩💖💖💖💖🥰🥰🥰🥰
Sir ji jis tarah aap physics ke chapters ko itne ache se smjhate h ki koi bhi doubt nhi reh jata ... Ici tarah chemistry chapters ki bhi aapke channel per videos ho to kitna badhiya h 💫💫✨✨✨🙏🙏🙏
1:00:52 sir yaha to 7 significant figure hoga na kyuki zero decimal k baad hai...aapne zero kyu consider nhi kiya significant figure me
Thanl you sir for explaining ncert line by line. Sir you explain in live class
Welcome🎉
You are explaining so nicely sir
This is perfect for ncert students ❤
1:27:14 sir isme 0.002308 me point 2 ke bad lane ke liye to multiply hi krenge 1000 se to apne screen pe divide kyu likha h??.
Basically isme multiply aur divide dono karenge.
Multiply kar k 2.308 ban jayega aur 1000 divide ho jayega.
To finally 1000 divide k form me hi aa jayega. So 10 to the power -3 hoga.
Actually ye 2 steps hai jise maine ek step me kiya to ye confusion hui hai.
Jab record kar raha tha to first step k hisaab se kiya. Jab edit kiya to second step k hisab se
@@cbseworldz thankyou for clearing my doubt sir. I understood it now.😇😊.
Thanks finally I also got line bt line explanation channel
Thank you so much sir . ❤
I love your lecture ❤😊😊😊
Sir you teaching way is very brilliant
Sir can u plx tell me r those topics removed for board exam only will these topics come in neet🤔...
Check out neet syllabus
Neet syllabus has nothing to do with board syllabus
Sir chapter explanation is very Good But sir notes Kya Krna hai Jese main Points kya kuch bta skta hai ? Help ho jaege
Very nicely u explained sir thnx for sharing 😊
Sar aap bohat acha explain karte ho 😮
Awesome explanation sir...🎉❤🥰
Thanku.... 🙏🙃😇🔥
Welcome🎉
Sir why the initial velocity is written as v in topic 2.10.1
For initial velocity NCERT uses "v nought" instead of "u"
So, initial velocity = v nought
Final velocity = v
What a great teacher ❤
sir , is there no complete chapter video for chapter 3 and so on , i have found chapter 1 and chapter 2 , while chapter 3 has 4 videos only , and no other chapter can be found
I'm sorry for that. Due to some reasons I wasn't be able to upload rest of the videos
@@cbseworldz ok sir , no problem , thanks for first 2 chapters tho.
Sir you teach very well
Super explanation and sound quality is also very good and text quality also
Samjhne wali video thi aur samjhane Wale aap thank you ❤
Welcome🎉
Really I found perfect channel to study thank you sir
Welcome🎉
Yussssss
2:22:09 sir here we have to do multiplication of 6 and 7.203 so we will take 7.203 as the no. Which contain less significant figure and in answer there will be only 4 significant figure. We didn't take the 6 here because the exact numbers like 3,4 have infinite no. Of significant figures. Am I right sir ?
Yes
Thank u so much ❤sir mujhe bohot ache se samajh aya but apka channel mujhe kafi late mila i m vry tensed ki ab itna sara syllabus kease complete hoga😢...
Welcome🎉
Sir isko rbse wale nhi dekh sakte hai kya 🤔
Agar NCERT chalti hai to dekh sakte ho
Thank you so so much sir for helping me to read NCERT physics book..
BEST EXPLANATION EVER.EXCELLENT
Thanks a lot sir ❤❤❤ ur are best teacher of physics❤❤❤ aap free me hamare liye itnaaa kuch provide krvaate ho essa koi nhii krtaaa without any charges aap sb video's provide krwaate ho ❤❤❤ u r really very beesssttt❤❤ no words for u 🫡 hat's of to you 🎩🫵🏻❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
You are most Welcome🎉
Sir aap bohot ache se explain karte ho
sir pls apki ncert reading ki zrurat NEET aspirants ko boht zyda hai. apse zyada bariki se koi teacher nahi pdata hai ncert. Sir pls kuch kijjye hme apki boht zrurat hai
Sir ji kya aap class 11th ke chemistry chapters per bhi videos upload krte h ??
Abhi to nahi kar rahe hai
@@cbseworldz but agar ho ske to please try krna chemistry chapters per because chemistry bhi ekdam smjh nhi aati... Hum sabhi students jitna ho ske aapko support krenge... I subscribe your channel.. like, comment, share and download your videos 😇😇🌟🌟🌟✨✨💫💫
Please don't download. Because main thing is watch time. If watch time is less then TH-cam will not recommend my videos to others as the algorithm will think that people are not liking the video that's why they are not watching it full.
@@cbseworldzok sir ji jaisa aap kho .. mujhe ye cheez nhi pta thi .. thanku btane ke liye...🙏🙏🙏🙇♀️🙇♀️🤗🤗☺️☺️
Thanku sir so much ❤
thanks alot , its super helpful!
Best Exzplanation😊
Keep going 🔥🔥🔥🔥🔥
Thankyou very much sir ❤
Sir you are a hero of physics ❤❤❤❤I am average student but I don't like physics but your vedios is totally changed my mind this time I like physics thank you sir more vedios send me please 🙏🙏🙏🙏🙏
Welcome🎉
Chapter-3 video also uploaded. Check it out!
@@cbseworldz sir all ncrt 11 or 12 apllod please sir I am neet drop students
Sir isme delete topic nhi the??
There are some students who study for knowledge rather than just passing the examination. So, I request you to make a part covering cutted portion of NCERT.
Yes, that's the best way of studying. I too prefer this. I decided to first complete the syllabus part then move to rest of the content.
I'll try my best to upload those videos also
@@cbseworldz24:43 Sir d omega toh andar wala angle hai aaor hamne d theta × d fi ko d omega se replace kiya hai toh ye inke multiplication se andar wala angle kahan se aagya matlab jo andar wala angle hai uska arcs ki length ke multiplication se kya lena dena aaor sir ek aaor baat ke ye angles ko d theta, d omega hi kyu liya simply Theta 1 aaor theta 2 lelete aaor arcs ki length bhi L1 aaor L2 le sakte the aisi ds d theta complicated chize kyun li?
Jaise aap ko agar rectangle ka area nikalna ho to length aur width ko multiply karoge. Jabki length aur width to ek boundary ki tarah hai. Usse andar ka area kaha se aa gaya.
Main chiz ye hai ki hum ek 2D concept ko 3D me introduce kar rahe hai. To agar 2D me humne arc liya tha to 3D me area lenge.
d omega dono plane angle k multiplication ki value nahi hai. Bas humne use replace kiya hai. Plane angle se solid angle derive nahi hua hai. Balki ye dono alag alag introduce hue hai. Yaha Maine solid angle ka derivation nahi kiya hai balki analogy explain ki hai ki jaise hum plane angle ko 2d me define kar rahe hai usi tarah 3d me hun solid angle ko define karte hai
"d" kya hai ye ap calculus me padhoge. Yaha par kisi object k ek portion le rahe hai. to ds ek small arc ko show karna hai. Ye fixed nahi hai. Jaise hum kisi chiz ki value ko "x" maante hai to uska matlab ye hai ki x ki jagah alag alag value aa sakti hai. ds ko jab hum integrate karenge limit laga k tab ja k value niklegi. Agar L1 le lenge to value nahi nikal sakti.
Angle k liye aap d theta1 d theta2 le sakte ho. No problem
Sir, in sab area ka toh derivation available hai rectangle circle etc but ye jo solid angle hai iska samajah nahi aaya matlab ke circle ka area pir^2 hai uska meaning hai ke kaise ek circle ko rectangle ke form me lake area nikalte hai aaor uska derivation available hai jaisa ki aapne kaha ke aap derivation nahi kr rhe aap analogy de rhe ye "analogy de rhe" ko todha detail me explain kijiyega aaor ho sake to ek iske derivation me video banayega
