A billiard ball of mass M , moving ...

A billiard ball of mass M , moving with velocity `v_1` collides with another ball of the same mass but at rest . If the collision is elastic , the angle of divergence after the collision is

A

`0^@`

B

`30^@`

C

`90^@`

D

`45^@`

Text Solution

Verified by Experts

The correct Answer is:
A
When billiard billiard ball collide elasticaly , they will exchange the kinetic energy , so that may move in stright path or at any angle .
