Four particles of mass m moving with speed v towards the centroid. If they collides and get stick then what will be the speed of the combination.

`v/sqrt(2)`

`4v`

`vsqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:

`vecP_(i) = vecP_(f)`
`therefore vecP_(i) =0 = vecP_(f) = 4mv`
`v = 0`
