Two particle which are initially at rest...

Two particle which are initially at rest move towards each other under the action of their internal attraction. If their speeds are `v` and `2 v` at any instant, then the speed of centre of mass of the system will be

A

2v

B

0

C

`1.5`v

D

v

Text Solution

Verified by Experts

The correct Answer is:
B
As intially both the particles were at rest therefore velocity of centre of mass was aero and there is no external force on the system so speed of centre of mass remains constant i.e , it should be equal to zero .
