P and Q are two identical masses at rest suspended by an inextensible string passing over a smooth frictionless pulley. Mass P is given a downward push with a speed v as shown in figure. It collides with the floor and rebounds. What happens immediately after collision ?
- P and Q both move upwards with equal speeds
- P and Q both move upwards with different speeds
- P moves upwards & Q moves downwards with equal speed
- Both P and Q are at rest.
Answer
(B) P and Q both move upwards with different speeds
