In the arrangement shown in figure, a block A of mass m has been placed on a smooth wedge B of mass M. The wedge lies on a horizontal smooth surface. Another block C of mass (M)/(4) has been placed in contact with the wedge B as shown. The coefficient of friction between the block C and the vertical wedge wall is mu= (3)/(4) . Find the ratio (m)/(M) for which the block C will not slide with respect to the wedge after the system is released?

A wedge with mass M rests on a frictionless horizontal surface A block with mass m is placed on the wedge. There is no friction between the block and the wedge. A horizontal force f is applied to the wedge. What magnitude F must have if the block is to remain at constant height above the table top?
