A ball of mass `1 kg` is thrown up with an initial speed of `4 m//s`. A second ball of mass `2 kg` is released from rest from some height as shown in Fig. Choose the correct statement (s).

A

The centre of mass of the two balls comes down with acceleration `g//3`.

B

The centre of mass first moves up and then comes down.

C

The acceleration of the centre of mass is `g` downwards.

D

The centre of mass of the two balls remains stationary.

Text Solution

Verified by Experts

The correct Answer is:
B
The initial velocity of `CM` is upward. The acceleration of the `CM` is `g` downward.
