A particle of mass m moving in the x direction with speed 2v is hit by another particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to

A

`sqrt(2)v` towards South-West

B

`sqrt(2)v` towards North-West

C

`sqrt(2)v` towards South-East

D

v towards North-East

Text Solution

Verified by Experts

The correct Answer is:
B
`v_(x)=-upsilon hat(j)`

`therefore v_(Y)=v_(YX)+v_(X)=-upsilon hat(i)+upsilon hat(j)`
`therefore |v_(Y)|=sqrt(2)upsilon`
Direction of `v_(Y)` is North-West.
