A pendulum bob of mass `m` connected to the end of material string of length `l` is released from rest from horizontal position as shown in the figure. At the lowest point the bob makes an elastic collision with a stationary block of mass `5m`, which is kept on a frictionless surface. Choose out the correct statement(s) for the instant just after the impact.

A

Tension in the string is `17/9 mg`

B

Tension in the string is `3 mg`

C

The velocity of the block is `(root2(2gl))/3`

D

The maximum height attained by the pendulum bob after impact is (measured from the lowest position) `(4l)/9`

A ball of mass 0.01 kg is suspended from a fixed point O by means of a light and inextensible string of length 10m. The ball is first taken aside such that string becomes horizontal and then released from reast. At the lowermost point of its path, it hits a stationary small block of mass 1.205kg lying on a rough horizontal surface.
