A spring block system with mass of block m and spring constant K (all the surfaces of blocks are perfectly abosrbing and smooth) is placed on a smooth horizontal plane as shown in the diagram at rest. A light beam of intensity l is switched on its right side. find the amplitude of oscillations of the block. (face area of block is A and c is the speed of light in vacuum)

A

`(l)/(Kc)A`

B

`(2l)/(Kc)A`

C

`(4l)/(Kc)A`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
