Watch till the end. Some important links are given on the end screen. Thank you 🙂.

sir Thanks alot , at 13.04 for net june 2017 qstion , should we write minus Fx for potential right? pls help,

[@poonamsain3464]

First question me equation 1 or 2 ke liye graph kaise banaya, please tell

[@tosifahmad4606]

The phase space trajectory of a single particle falling freely from height is?

[@rahulmeena7208]

Good satisfaction of all questions

[@ambarnafees5845]

Sir what will be direction of trajectory in Q-2

[@meghajoshi6442]

Sir, Excellent vdo. One querry. In Q8, Option( c) is similar to option ( a). Then why (c) is NOT the correct option. What is wrong in option C?

[@physicshub]

Nice observation. Well, in option (C) the phase space trajectories are looking like perfect ellipses which is the case when the given potential is kx^2 type. But in this case there is an extra term in the potential of type kx^4. So this should not give perfect ellipses. Hope this will clarify your doubt.

@@physicshub yes Sir. I understood. Thank you for quick reply. 🙏

[@piyalibanerjee3376]

Thank u so much sir.it is really helpful

[@tosifahmad4606]

Thanks Sir Have PDF copy

[@HarpreetKaur-mj3vu]

Plz explain question 3 of replusive potential in some other way...if possible.. this way is not too much clear

[@madhusmitapanda1294]

Sir pls volume thoda increase kijie aapna Sunai nhi deta aapka awaz clr se Slow sunai derha h

[@reshmahittalamani6600]

What is E sir?

[@itishreesargam9053]

Sir but the answer from Dec 2017 is wrong..coz there are two Maxima..so how can..closed ellipse can be formed for phase space..

[@rkn8109]

Thanks alot

[@rahulsolanki8266]

In qus 9 how u assume q please tell

[@physicshub]

look at the integrand.The q is chosen looking at it so that we can carry out the integration.This type of integration we have done in higher secondary mathematics.Got it now?

[@rahulsolanki8266]

No..

[@physicshub]

Take a class 12 mathematics book and look at the chapter where there are integrations involving trigonometric functions.Solve some of them and you will be able to understand it.Here it is purely mathematical integration.

[@physicshub]

I didn't assume it to be ellipse. It will not be a perfect ellipse but it has a shape similar to that. Here the shape is not bothering us. We are just integrating with the data given in the question. Hope this will answer your query.

Sorry.. But it is not helpful.

[@physicshub]

Sorry for it. We will try to improve our contents. Thanks for the feedback.
