Question

A ball moving with a certain velocity hits another identical ball at rest. If the plane is frictionless and collision is an elastic oblique collision, the angle between the directions in which the balls move after the collision, will be (A) 30°  (B) 60°  (C) 90°  (D) 120°

This is an example of elastic oblique collision. When a moving body collides obliquely with another identical body in rest, then during elastic collision, the angle of divergence will be 90°

$3 0^{\circ}$

$6 0^{\circ}$

$9 0^{\circ}$

$12 0^{\circ}$

This is an example of elastic oblique collision. When a moving body collides obliquely with another identical body in rest, then during elastic collision, the angle of divergence will be $9 0^{\circ}$
