@ 13:50 Application of virial theorem guarantees that total energy remains negative even after the force is changed. So no way for the new orbit to be parabola. Also going through virial theorem doesn't involve the velocity factor. The velocity may or may not change. So virial theorem is safer route to go for this problem as far I understand and the new orbit should be elliptical
People are saying that velocity is constant with time , yes but that's correct in case of uniform circular motion , there is not mention about uniform circular motion , so hope someone challenge this question
sir, in question no 16, they have mentioned the ionization energy of hydrogen atom as -13.6 eV. So, here, whenever we calculate the wavelength for hydrogen atom, is there any need to consider the reduced mass? If not, then after considering the reducd mass of deuterium only, the ans becomes ( - 0.03) and that was also an option in that question. sir Please clear the confusion.
if Shameem sir teaching the physics it becomes quite interesting and no more boring... thanks god to make such a great teacher in the universe ...
This is the beauty of great teacher 🙏..
Legend of physics Samim sir .. really ❤❤
thanks to this youtubers, I got jrf in last exam.
Thanks sir🙏

By using virial theorem Energy comes out be negative , so there is elliptical orbit .

Shamim sir is always best ❤ love u sir . 💚
Question was really tough. I attempt 9 from part A, 12-14 from part B and 9-10 from part C only. Total 105-110 attempt kar paya 😢😢

Let's see what answer nta gives. We have not used ionization energy anywhere in our calculation so the answer we are getting should be correct.
Samir sir is best...Jalwa h sir ka
Thanks sir
Hello sir
Do you have any online learning platform for Net other than youtube.

It is unit mass take mass one in Q6
Sir please Reference book
How many questions are there which have wrong answer in provisional answer key. especially from part A
Personally didn't find any answer in part A that was given wrong apart from question id 1006
Also from part B, C every answer seemed spot on
is there any wrong answer in pro....answer key
Naah don't really think that
