Answer
both A and R are true and R is not the correct explanation of A
Explanation
Assertion (A) is true because the cricketer pulls his hands back to increase the time over which the ball’s momentum is reduced to zero. This reduces the force on his hands as per Newton's second law of motion which is :
So, on increasing time (Δt) reduces the force (F) experienced.
Reason (R) is true because this is Newton’s third Law, which is correct in itself, but it is not the reason why the cricketer withdraws his hands as the reason involves Newton’s second law.
