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

-V and 2V
2V and -V
V and -2V
-2V and V

detailed solution

Correct option is D

Due to elastic collision of bodies having equal mass, their velocities get interchanged.
