JEE MainPhysicsCenter of MassMCQ+4 / −1
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Body 'P' having mass M moving with speed 'u' has head-on collision elastically with another body 'Q' having mass 'm' initially at rest. If m << M, body 'Q' will have a maximum speed equal to '2u' after collision. Reason R : During elastic collision, the momentum and kinetic energy are both conserved. In the light of the above statements, choose the most appropriate answer from the options given below :
- AA is correct but R is not correct.
- BA is not correct but R is correct.
- CBoth A and R are correct and R is the correct explanation of A.
- DBoth A and R are correct but R is NOT the correct explanation of A.
