Question: A particle of mass m moving with a velocity \(\overrightarrow{V}\) makes a head on elastic collision...

A particle of mass m moving with a velocity V→\overrightarrow{V} makes a head on elastic collision with another particle of same mass initially at rest. The velocity of the first particle after the collision will be

A

V→\overrightarrow{V}

B

−V→- \overrightarrow{V}

C

−2V→- 2\overrightarrow{V}

D

Zero

Answer

Zero

Explanation

Solution

In perfectly elastic head on collision of equal masses velocities gets interchanged
