A long block A of mass M is at rest on a smooth horizontal surface. A small block B of mass 
is placed on A at one end and projected along A with some velocity v. The coefficient of friction between the block is 
. Then, the accelerations of blocks A and B before reaching a common velocity will be respectively
A
(towards right), 
(towards left) B
(towards right), 
(towards left) C
(towards right), 
(towards left) D
(towards right), 
(towards left)
Text Solution
Verified by ExpertsThe correct answer is:
C
The force causing the motion of A is frictional force between A and B,
So, acceleration of A,
Block B experiences friction force toward left,
