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

    A)  Both A and B rise to 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

    Correct Answer: D

    Solution :

    Due to the same mass of A and B as well as due to elastic collision velocities of spheres get interchanged after collision. Hence, the correction option is [d].
