Block B of mass m has been placed on block A of mass 3 m as
shown. Block A rests on a smooth horizontal table. F1 is the
maximum horizontal force that can be applied on the block A such
that there is no slipping between the blocks. Similarly, F2 is the
maximum horizontal force that can be applied on the block B so that
the two blocks move together without slipping on each other. When
F1 and F2 both are applied together as shown in figure.
