A system is pushed by a force F as shown in figure All surfaces are smooth except between B and C is mu . Minimum value fo F to prevent block B from down ward slipping is

A system is pushed by a force F as shown in figure All surfaces are smooth except between B and C is mu . Minimum value fo F to prevent block B from down ward slipping is

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
