A block A of mass m kg lies on a block B...

A block A of mass m kg lies on a block B of mass m kg. B in turn lies on smooth horizontal plane. The coefficient of friction between A and B is `mu`. Both the blocks are initially at rest. A horizontal force F is applied to lower block B at t = 0 till the lower block B undergoes a displacement of magnitude L. Match the statements in Table-1 with the results in Table-2.
