Sure...but my experience is you already know them...🤔

Siir how can I became pro at physics?? ❤

Sir plz reply, how can I become pro at physics?

Sure....i will reply in detail...just wait for sometime

@@doubtdestroyer plz sir reply me when you are free

It’s my pleasure 😊...i could help you...keep smiling and keep learning...

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

Thanks for your appreciation but I am just beginner....

Glad to hear that 🙏...it means a lot...

Sorry to hurt your emotions...but I am not God ...I am just starting my teaching career...

​@@doubtdestroyer, 💝💝❤️❤️❤️❤️💘💝💝

Let us suppose we have a spring of natural length l and spring constant k and two masses m1 and m2. Now suppose we have centre of mass at origin. Let position of m1 is x1 and that of m2 is -x2. So expansion of spring will be x1+x2-l. Now since CM is at origin so m1 x1 = m2 x2 and m1 v1 = m2 v2 . Now use conservation of energy and let maximum compression in spring is Xmax then 1/2 k(Xmax)^2 = 1/2 k ( x1+x2-l)^2 + 1/2 m1 (v1)^2 + 1/2 m2 (v2)^2. If you use these general equations you can get whatever you want. Or you can also use reduced mass method in which you replace both block by a single block of mass M= m1×m2 / (m1+m2). Frequency will be same and for displacement and velocities use above mentioned equations.

@doubtdestroyer sir my doubt was ki apn ek block jese m1 ke displacement as a function time kese likhege? Bcuz wo aage bhi jaa rha hai n com ke frame mai shm bhi kr rha hai....

Frequency who have to find by the above method. if initial or final expansion of spring is given then you can easily calculate amplitude. Then just write shm equations as you know X1 = A1 sinwt. A1 m2 = A2 m1. If you are still confused...I will make a video on it...

@@doubtdestroyer sir please make a video on it as I'm confused 😕

Wait...aa jayenge... don't worry...may be on Sunday

@doubtdestroyer ok sir...

Thank you 🙏

Sure

Yes... brother...I am planning to launch a course in the next session and I will follow this book so you can understand the level. of books

It's best book ..few topics are missing but whatever is there that is best...i suggest otherwise because you said you don't have any teacher. It's slightly difficult book .

You can get 100 percentile...no doubt about the Book.. physics galaxy books are my first priority

@@doubtdestroyer Really thanks brother for your time. Just last question Kya iske theory sufficient h? Mtlb kya agr ma ye book acche se padhu for theory to mujhe kese bhe teacher ya fir coaching ke jarurat nhii hoga na theory ke liye. . Is It's theory is sufficient for jee mains and advance. Yes some topics are missing but I will cover them. Through my other resources. But iske theory sufficient h na jee advance ke liye?? ❤? plz tell

As far as theory is concerned both Books are good. Since you are asking at this time dec and I am considering you are in 11 standard and you do not have anyone who can clear your doubts then Cengage will be better for you.

Most welcome 🙏

Yes you can proceed because the remaining chapters of class 11 SHM KTG THERMODYNAMICS WAVES do no need mastery over rotation & fluid mechanics. If possible just have slight overview of these topics because sometimes there can be mixed concepts problems. So don't worry...just proceed as you are planning. Thanks for your appreciation 🙏.. Keep smiling and keep learning..

Ha ha 😆😆

Sure...

Telegram channel is there ...link in the about section...feel free to ask doubt...

@doubtdestroyer we are not allowed to send there it says

@DGX739 send in the comment section of latest post..

@@doubtdestroyer SIR i need to send some screenshot .

@@DGX739 you can send them ...it's allowed..

If you are unable to understand some solutions then may be there is some typo or misprint or concept which are not read by you yet or there can be really some misunderstanding of concept. So the most important part is - if you are able to solve practice problems without any hint , then there is no problem but if not then conceptual understanding is lacking. Hope it helps...

Sure...any specific question ?

Yes sir in byu 20,27,30 thankyou sir

Sure....but wait ..till tomorrow or day after tomorrow..

@doubtdestroyer thank you Sir

The solution is uploaded...you will get it at 5 AM . Keep smiling and keep learning Please share as much as possible 🙏

Thank you

Thank you 🙏

Good try....but correct answer is D. For better understanding you can watch this shorts completely.

​Yep , sorry I didn't read the options correctly, actually i have done same question but there was stone at the place of coin and there in option B. it was l decreases and h also decreases.😊@@doubtdestroyer

Most welcome ..

Sure...

Welcome... keep smiling and keep learning

Yes...dekho analysis m angle ki need hi nahi padi

​@@doubtdestroyer, Okay Sir ❤❤❤❤❤❤❤❤❤

Thanks and welcome
