In the arrangement shown in the figure, mass of the block B and A is 2m and m respectively. Surface between B and floor is smooth. The block B is connected to the block C by means of a string-pulley system. If the whole system is released, then find the minimum value of mass of block C so that A remains stationary w.e.t. B. Coefficient of friction between A and B is `mu.`

In the arrangement shown in the figure mass of the block B and A are 2m , 8m respetively. Surface between B floor is smooth. The block B is connected to block C by means of a pulley. If the whole system is released then the minimum value of mass of the block C so that the block A remains stationary with respect to B is: (Coefficient of friction between A and B is mu and pulley is ideal).

The figure an L shaped body of mass M placed on smooth horizontal surface. The block A is connected to the body by means of an inexiensible string , which is passing over a smooth pulley of negligible mass.Another block B of mass m is placed against a vertical wall of the body. Find the minimum value of the mass of block A so that B remain stationary relative to the wall. Coefficient of friction between the block B and the vertical wall is mu .

In the system shown, the blocks A,B and C are of weight 4W, W and W respectively. The system set free. The tension in the string connecting the blocks B and C is

In the arrangement shown in figure what should be the mass of block A , so that the system remains at rest ? Neglect friction and mass of string.

In the given situation, what is the minimum mass of block A so that block B remains stationary with respect to the wall? The coefficient of friction is mu between wall and block. All other surfaces are smooth.

Three blocks are placed as shown in figure. Mass of A, B and C are m_(1), m_(2),"and "m_(3) respectively. The force exerted by block 'C' on 'B' is :-

In the arrangement shown in figure, pulley and string are light. Friction coefficient between the two blocks is mu whereas the incline is smooth. Block A has mass m and difference in mass of the two blocks is deltam . Find minimum value of m for which the system will not accelerate when released from rest.

In the arrangement shown in the figure the system is in equilibrium. Mass of the block A is M and that of the insect clinging to block B is m. Pulley and string are light. The insect loses contact with the block B and begins to fall. After how much time the insect and the block B will have a separation L between them.

In the arrangement shown in Fig there is no friction between of mass 2m and ground but there is friction between the block of masses m is stationary with respect to block of mass 2m The value of friction between m and 2m is

In the diagram shown, the block A and B are of the same mass M and the mass of the block C is (M_(1)) . Friction is present only under the block A. the whole system is suddenly released from the state of rest. The minimum coefficient of friction on keep the block A in the state of rest is equal to .
