An object of mass 3m splits into three equal fragments. Two fragments have velocities `vhatj` and `v hati`. The velocity of the third fragment is

A

`v(hatj - hati)`

B

`v(hati - hatj)`

C

`-v(hati + hatj)`

D

`(v(hati +hatj))/(sqrt2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`mvhati + mvhatj + mv_3 =0`
`implies v_3 = -v(i+j)`
