Two identical particles moves towards each other with velocity `2v and v` respectively. Two velocity of centre of mass is …………..

A

`v`

B

`(v)/(3)`

C

zero

D

`(v)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
D

`v_(cm)=(m_(1)v_(1)+m_(2)v_(2))/(m_(1)+m_(2))=(m(2v)+m(-v))/(m+m)=(v)/(2)`
