In the figure shown, friction exists between wedge and block and also between wedge and floor. The system is in equilibrium in the shown position.

In the figure shown coefficient of friction between block A and ground is 0.4 and that between wedge and block B is zero. Wedge is fixed. Find tension is string and acceleration of block A if F = 28 N.

Calculate angle of friction between wedge and block system is at rest M coefficient of friction between wedge and block.

Calculate angle of friction between wedge and block system is at rest M coefficient of friction between wedge and block.

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

If the coefficient of friction between the wedge A and block B shown in the figure is mu , then the maximum possible horizontal acceleration of A for which B doesn’t slip is [ angle of inclination of wedge = 45^@ ]
