47:00 solve this question using simple electrostatic Force method... without the potential energy concept. Find 2Fcos° and divide this F/m = a and get the acceleration. Put it in V2= U2+2aS And get the V = approx 6m/s (use calculator at last) As simple as that
Sir U Are Just a Legend....The way you give us to feel understand the main difference between Electrostatic Potential(V) and Electrostatic Potential energy(U) is just awesome...thank u very much sir....May God Bless u...lots of love sir...
43:31 the work should be negative There is a very small calculation mistake Otherwise its correct Ans: -4.5 * 10^-3 J You can imagine this by : hamko -ve charge ko +ve ke baju me lana hai to +ve wala usko already attract kar rah hoga or hamko Speed constant rakhni hai to hamko external force opposite direction me lagani padegi. As a result displacement or force opposite honge to angles hoga cos(180*) as a result work done by external force in bringing -ve charge of 1uC from infinity to x=2 is (-4.5 * 10^-3 J)

@INFURNUS Walker #19496 see playlist and ncert and watch vedios accordingly. Make notes(very imp) though you will get alakh sir's notes. But you can understand them if you will make your own notes.
Sir really gives us fellings about the concept means actually what's really happenings. Thanks a lot to the greatest teacher ever I have seen . Hates off .❤️❤️❤️
Okay Guys I must tell this here that I was solving a Q and I was just stuck at one point as I was not at all thorough with the concept because during my classes or even watching sir's lecture I try to ignore the concept and focus more on formulas and here I am. After watching this lecture I can say that now atleast this concept has found a place in my mind. So I just wanna highlight here that getting the concept is more important than cramming the formulas.
There are huge number of viewers but the like are just 16 k What happened guys ..if he is doing huge efforts ...so we hafta appreciate him ...don't forget to hit like 💯❤️
Sir, I fell in love with physics with your explanation. Simple yet profound. Not caring for marks or competition, just for the love of the subject, the easy and laid back approach, the intimation that there's something much more valuable than marks or such trivial matter. Overall the joy that radiates in your teaching, it's contagious. Just for the love of the subject. Brilliant sir, please carry on.
Schools open ho gye sb log School coaching Jane lage but mai 2 saal phle bhi online padh rhi thi aur abhi bhi wahi Sahara hai kyuki corona ke time se hm log village aa gye hai . Village me prblms hai but thanku sooo much sir you make my journey easy 😊 ☺ 🙏. You Don't know how much l have respect for you.
Guys..around 31:14 there's one sum in which sir has done the combination method to check the combinations of system but you can also try the way {n(n-1)}/2.. you will get the total no of combinations...
May be their is one more solution for last question[Q5]:- We can calculate net force acting on the charge q3 which is downward which is coming 4.6 x 10^-3N Then we can find acceleration on charge q3 using a=F/m, acceleration(a)= 4.6 m/s2 Then we can apply equation of motion, v^2=u^2 + 2as Also initailly charge was at rest then u=0 v^2=2as= 2 × 4.6 × 4 v^2=36.8 v=√36.8 v=6.06 m/s means v is approx 6 m/s. NOTE=I don't know whether this solution is right or wrong. But it required less calculation.

How to find electrostatic potential energy for two charge system.. th-cam.com/video/pr48JyY8dvU/w-d-xo.html #vikasclasses,#physicsmasti #JEE2020#neetug, #physics
In the last question, can we use use U(final) - U(initial) = Work done..... from this work done (W = m.a.s.) We can calculate acceleration and the using third equation of motion velocity can be calculated and ans is also same... please comment if i am wrong.....
Sir yadi pahle force nikal liya jaye q3 ke upar, uske bad acceleration aa jayega , aur phir hum direct third law of motion use ka lenge,. V square- u square=2as laga de aur yaha se hamara v nikal aayega

43:31 the work should be negative
There is a very small calculation mistake
Otherwise its correct
Ans: -4.5 * 10^-3 J
You can imagine this by : hamko -ve charge ko +ve ke baju me lana hai to +ve wala usko already attract kar rah hoga or hamko Speed constant rakhni hai to hamko external force opposite direction me lagani padegi.
As a result displacement or force opposite honge to angles hoga cos(180*) as a result work done by external force in bringing -ve charge of 1uC from infinity to x=2 is (-4.5 * 10^-3 J)
Yeha dono +ve charge hai, repulsion hoga
Hume force de ke body ko lana padega

I think this is helpfull 👍👍🤩
Thnkuuu ✌️
43:16
I did the problem exactly in that way by myself... (In sir's language pause karke....)
49:49
why u not use work done = change in kinetic energy
work done=change in potential unergy
change in kinetic energy=change in potential energy
Yeah i did the same, it is a shorter approach Btw both are correct.
Sir I am securing good marks in physics just because of you only
Love you sir..........
😊😊😊😊😊😊
Me too got highest in physics in 11 hoping same in 12th
Nice
@@rajraj-pu5uo bhai aapko alakh sir ke website mili
Kya
@INFURNUS Walker #19496 ncert se chapter wise hi pdho
@INFURNUS Walker #19496 see playlist and ncert and watch vedios accordingly. Make notes(very imp) though you will get alakh sir's notes. But you can understand them if you will make your own notes.
Masterpiece Lecture 🔥👏👏
42:45 it will be 1+1/2
Sir really gives us fellings about the concept means actually what's really happenings. Thanks a lot to the greatest teacher ever I have seen . Hates off .❤️❤️❤️
Okay Guys I must tell this here that I was solving a Q and I was just stuck at one point as I was not at all thorough with the concept because during my classes or even watching sir's lecture I try to ignore the concept and focus more on formulas and here I am. After watching this lecture I can say that now atleast this concept has found a place in my mind. So I just wanna highlight here that getting the concept is more important than cramming the formulas.
yes same thing happened to me and now here I am trying to clear my concepts through sir's videos :'((
Sir your efforts towards us for our education is mind-blowing ...HATS OFF to this man 🎩
You are right
26:24 , 44:26 legend who follow sir for 11th class know these same q in gravitation ch 😄😄😄😄😄

Is another method too
There are huge number of viewers but the like are just 16 k
What happened guys ..if he is doing huge efforts ...so we hafta appreciate him ...don't forget to hit like 💯❤️
Sir you are the turning point of my life Thank you sir for making physics more interesting
Sir, I fell in love with physics with your explanation. Simple yet profound. Not caring for marks or competition, just for the love of the subject, the easy and laid back approach, the intimation that there's something much more valuable than marks or such trivial matter. Overall the joy that radiates in your teaching, it's contagious. Just for the love of the subject. Brilliant sir, please carry on.
Schools open ho gye sb log School coaching Jane lage but mai 2 saal phle bhi online padh rhi thi aur abhi bhi wahi Sahara hai kyuki corona ke time se hm log village aa gye hai . Village me prblms hai but thanku sooo much sir you make my journey easy 😊 ☺ 🙏. You Don't know how much l have respect for you.
When he says at least try one feeling comes that we have to try there is magic in his words
Number of system= n*(n-1)/2. where n=no of charges!
Works all the time.
Guys..around 31:14 there's one sum in which sir has done the combination method to check the combinations of system but you can also try the way {n(n-1)}/2.. you will get the total no of combinations...

Boht Hard,,Boht hard
Perfect 😂💯
Thank you sir...... To make physics easy....... Love you sir
Thank you so much sir for this amazing lecture🤩🙏🙏
All Time best 🏋️ sir jiiii
Hmare zamane mei ek teacher hua krte the jo ek white board or pen le kr puri physics pdha dete the❤🩹
thank u sir...btw looking smart.....
Hihihi
SADHI KAR LO
May be their is one more solution for last question[Q5]:-
We can calculate net force acting on the charge q3 which is downward which is coming 4.6 x 10^-3N
Then we can find acceleration on charge q3 using a=F/m,
acceleration(a)= 4.6 m/s2
Then we can apply equation of motion,
v^2=u^2 + 2as
Also initailly charge was at rest then u=0
v^2=2as= 2 × 4.6 × 4
v^2=36.8
v=√36.8
v=6.06 m/s
means v is approx 6 m/s.
NOTE=I don't know whether this solution is right or wrong. But it required less calculation.
True
This is the best teacher i have ever seen
Sir question 5
When we solved we ignore the (-) sign of 4 microcoulomb charge.
God blessed sir...u r so brilliant teacher I respect and appreciate u really sir.....best teacher for physics in whole universe

kya kru main mar jao?
😂😂😂😂😂
true bro
😂😂😂
Feel da power of maths jk 😜
Permutation combination agar samajh nahi aa raha hai to ye formula lagao ho jayega - n(n-1)/2
Thankyou For An Amazing Session Sir 🙂
You are doing a great Job Sir
sir (time=30min28sec) sir its actually 3!/2!(3-2)! .....but u have written 3!/2!(3-1)!....finally answer u have written correctly.....thank u sir ... big fan of urs
Yes sir Question no. 4 mai bhii Vp-V infinity vala concept lgaya ussey bhi same answer mene try kiya ho gya -kq1/2+Kq2/1=Wext/q3 Thanku sir Bohot achha explain karte ho or Feel aata h physics padhne mai aapsey mza aa jata h
Respected Sir thank u so much sir...actually starting listening ur organic chemistry(which i hate) classes... But now i am keeping more interest to GOC.. i am luckiest to hve u sir... Thank u sir for teaching us with loads of love...
mere into bhai....tu GOC ka comment is chapter pe karega tho iss chapter ka comment kahe pe jake karega.... redox meh..... such a comical men
Arey..bhai.. 😁😂 i think u hve to read the comment once again...yes i have to keep the msg in the goc ..but he is physics wallah😈..mann..damnnn... Its not the matter which subject he was teaching.. I came here to appreciate and thank him .. For his wonderful explanation... But bhai.. Its a 'comical man' not men... 😂😁😇🙏
I can understand Physics only because of you sir! Thank you sooo muchh sir.... Cant tell you what kind of help you are doing to students like me❤
Tq sir. 🙏........ for help us in any how condition..........🤗😊😊😊🤗🤗🤗
Sir agr infinity se kisi charge ko lane me work done 0 hoga to kisi charge ka potential bhi to 0 ho jayega kuki
V= Wext agent~->a/q°
1:08 Achanak sir ne *Helium* gas inhale kar liya😂😂
Bio students (also me )be like: ok we are gonna count instead of using this combinations😑
😂😂
You can use n(n-1)/2
30:00 😥

Best teacher i have ever seen ❤❤❤❤
Yes sir, At 43:12 , I used that alternate method(finding potential first, and then dividing it by q3). Thank you sir, you are amazing.. 😍😍
same bro
Sir ji
Assignment bohot cool bohot cool ....🎆🎉🎉🎊🎇😎😎😍
I love physics because of you sir 🙏😇😍 thank you so much sir
sir in last question there is a doubt
u hv considered initial potential energy as only electrostatic potential energy but there should be gravitational potential energy too of mgh = 1/1000 ×10× 4
can anyone clear my doubt??
Nope as there is no conservative force buddy written in top
@@suhanmohanty5713 to gravitational force to conservative he
It should be mention that it is gravity free space
bhai electrostats mein jabtak mentioned na ho tabtak gravity mat daal

In the last question, can we use use U(final) - U(initial) = Work done..... from this work done (W = m.a.s.) We can calculate acceleration and the using third equation of motion velocity can be calculated and ans is also same... please comment if i am wrong.....
@@shubhkawa2960 conservative force depends only on initial and final position not on the path taken..
Sir yadi pahle force nikal liya jaye q3 ke upar, uske bad acceleration aa jayega , aur phir hum direct third law of motion use ka lenge,. V square- u square=2as laga de aur yaha se hamara v nikal aayega
