Passage

Read the passage given below and answer the questions that follow:

A system consists of block A and B each of mass m connected by a light spring as shown in the figure with block B in contact with a wall. The block A compresses the spring by 3mg /k from natural length of spring and then released from rest. Neglect friction anywhere.

Block system with 2 blocks A and B

Block System With 2 Blocks a and B

In above figure we show that block A and B which connected with spring.
