The bob A of a simple pendulum is released

Your Ultimate Guide to JEE & NEET Question Solutions

The bob $A$ of a simple pendulum is released when the string makes an angle of ${45^o}$with the vertical. It hits another bob $B$ of the same material and same mass kept at rest on the table. If the collision is elastic

A

Both $A$ and $B$ rise to the same height

B

Both $A$ and $B$ come to rest at $B$

C

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

D

A comes to rest and $B$ moves with the velocity of $A$

The bob $A$ of a simple pendulum is released when the string makes an angle of ${45^o}$with the vertical. It hits another bob $B$ of the same material and same mass kept at rest on the table. If the collision is elastic

Due to the same mass of $A$ and $B$ as well as due to elastic collision velocities of spheres get interchanged after the collision.
