Two identical blocks A and B of mass m joined together with a massless spring as shown in figure are placed on a smooth surface. If the block A moves with an acceleration `a_0`, then the acceleration of the block B is

A

`a_0`

B

`-a_0`

C

`F/m-a_0`

D

`F/m`

Text Solution

Verified by Experts

The correct Answer is:
C
Acceleration of centre of mass `=(F)/(2m)`
`a_(CM)=(m_1a_1+m_2a_2)/(m_1+m_2)`
`:. (F)/(2m)=((m)(a_0)+(m)a_2)/(2m)`
`:. a_2=F/m-a_0`
