Question

A sphere of mass m equal to 2 kg collide with sphere of mass 3 kg which is at rest mass m1 will move at right angle to the line joining centre of the time of collision if the coefficient of restitution is

Answer 1

Answer:

Correct option is

C

32

By momentum conservation m1u1cosθ=m2V2⟶(1)

By newton's law of restitution (e)

e=u1cosθ−0V2−0=m2m1 

e=32
