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 :
1
Both A and R are correct and R is the correct explanation of A.
2
Both A and R are correct but R is NOT the correct explanation of A.
3
A is correct but R is not correct.
4
A is not correct but R is correct.
