Two blocks A and B of mass mA and m9 respectively are kept in contact on a frictionless table. The experimenter pushes the block A from behind so that the blocks accelerate. If the block A exerts a force F on the block B, what is the force exerted by the experimenter on A?

Answer :

Let be the force by the experimenter.

From the FBD of block A,


From the FBD of block A,


equation (1) becomes,

Equating acceleration from both the equations, we get

Thus, answer is,
