If is problem - 57 all situation are same expect force is applied on block C as shown in figure in case (b) Minimum value of F to prevent block B from downward slipping is

Wedge is fixed on horizontal surface. Block A is pulled upward by applying a force F as shown in figure and there is no friction between the wedge and the block A while coefficient of friction between A and B is mu . If there is no relative motion between the block A and B then frictional force developed between A and B is

There block A B ,and C of equal mass m are placed one over the other on a frictionless surface (table) as shown in figure The coefficient of friction between any blocks A ,B and C is mu The maximum value of mass of block D so that the blocks A,B and C move without slipping over each other is
