Question

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 $2 u$ 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:
