Physics Spl

Yes, Physics, Maths and Chemistry is compulsory if you want to do B.Sc (Hons) in physics. There might be some colleges in which it might not be required but in most of the colleges and universities it is an important criteria for admission. So, you have to do your own research in that case.
Hope this helped.

For getting admission in Manipal, you have to clear it's entrance exam which is MU-OET.

B.Sc Physics have lot of scope in the research wing. Astrophysics, Aeronautical Science, nano-science, Material Science etc. Are further field of study. You can go for M.Sc. And then for Ph.D.

Relative Velocity
When two objects are in motion, then velocity of one object w. r. t the other is called relative velocity. A and B both are moving on ground. Lets decide that ground is the one at rest, then
VA or VAg is velocity of A as observed by a person on ground also known as absolute velocity. VB or VBg is velocity of B as observed by a person on ground also known as absolute velocity. VAB is velocity of A as observed by B. VAB= VA- VB
VBA is velocity of B as observed by A. VBA= VB- VA.

No. EEE is dealing with lot of physics related aspects. Go for what is your like field of study.

You can go to AUCET office located at Pedawaltair (Vijaya Nagar Palace) near Eye Hospital and ask them. Or, you can go to Central Library located on China, Waltair Road near convocation hall. I forgot the name of the library. Go to Xerox section in that library and ask him about the question papers, he will provide you.
