Two identical particles move towards each other with velocity 2 v and v respectively. The velocity of centre of mass is

A

v

B

`(v)/(3)`

C

`(v)/(2)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
c
`V_(cm) = (m_(1)v_(1) + m_(2) v_(2))/(m_(1)+m_(2))[m_(1) = m_(2) = m, 2v = v_(1), v_(2) = -v]`
