In the diagram shown, friction is present only between therod and the wall. The mass of the rod is M and tht of the wedge is 3M. What is the minimum value of the coefficient of friction between the rod and the wall so that rod remains in the state of rest?

a Block of mass m is placed on a wedge of mass M there is no friction between the block and the wedge .The minmum coefficient of friction between the wedge and the gound so that wedge does not move is,

a Block of mass m is placed on a wedge of mass M there is no friction between the block and the wedge .The minmum coefficient of friction between the wedge and the gound so that wedge does not move is,

A wedge of mass 2m and a cube of mass m are shown in figure. Between cube and wedge, there is no friction. The minimum coefficient of friction between wedge and ground so that wedge does not move is

In the shown, A and B of equal mass are in equilibrium. Only surface between A and wall is rough. The minimum value of coefficient of friction is sqrtn. The value of n 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 .

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