A ball of mass 'm', moving with uniform speed, collides elastically with another stationary ball. The incident ball will lose maximum kinetic energy when the mass of the stationary ball is

A

m

B

2 m

C

4 m

D

Infinity

Text Solution

Verified by Experts

The correct Answer is:
A
If mass = m
First ball will stop `implies` v = 0
So k.e.=0 (min)
In other cases there will be some kinetic energy
(KE. can.t be negative)
