Question: A ball of mass m moving with velocity V, makes a head on elastic collision with a ball of the same mass moving with velocity 2V towards it. Taking direction of V as positive velocities of the two balls after collision are [MP PMT 2002]
Options:
A) $ -V $ and $ 2V $
B) $ 2V $ and $ -V $
C) V and $ -2V $
D) $ -2V $ and $ V $
