The bob `A` of a simple pendulum is released when the string makes an angle of `45^(@)` with the vertical. It hits another bob `B` of the same meterial and same mass kept at rest on the table. If the collision is elastic, then

A

Both `A and B` rise to the same height

B

Both `A and B` comes to rest at `B`

C

Both `A and B` move with the same velocity of `A`

D

A comes to rest and `B` move with the same velocity of `A`

Text Solution

Verified by Experts

The correct Answer is:
D
Due to the same mass of `A` and `B` as well as due to elastic collision velocities of spheres get interchanged after the collision.

A nail is located at a certain distance vertically below the point of suspension of a simple pendulum. The pendulum bob is released from a position where the string makes an angle of 60^(@) with the vertical. Calculate the distance of nail from the point of suspension such that the bob will just perform revolutions with the nail as centre. Assume the length of the pendulum to be one meter.
