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

A

2 v

B

zero

C

1.5 v

D

v

Text Solution

Verified by Experts

The correct Answer is:
B
As no external force is acting on the system , the centre of mass must be at rest i.e, `v_(CM) = 0`
