The coefficient of friction between two blocks is u1 and that between the block of mass M and the horizontal surface is u2. What is maximum horizontal force can be applied to the lower block so that the two blocks move without separation?

A block of mass m is placed on another block of mass M, which itself is lying on a horizontal surface. The coefficient of friction between two blocks is u1 and that between the block of mass M and the horizontal surface is u2. What is maximum horizontal force can be applied to the lower block so that the two blocks move without separation?

A block of mass m is placed on another block of mass M each of mass m. The system is released from rest. If accelerations of blocks A and B at any instant (not initially) are a1 and a2 Figure shows two blocks respectively then
