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

zero

C

1.5V

D

V

Text Solution

Verified by Experts

The correct Answer is:
B
Net external force on system is zero .
so `vecc_(cm)=zero`
