A force F is applied on the top of a cube as shown in the figure. The coefficient of friction between the cube and the ground is mu . If F is gradually increased, find the value of mu for which the cube will topple before sliding.

A force of 100N is applied on a block of mass 3kg as shown in the figure. The coefficient of friction between the surface and the block is mu=(1)/(sqrt(3) . The friction force acting on the bock is.

An equilateral prism of mass m rests on a rough horizontal surface with coefficient of friction mu . A horizontal force F is applied on the top of prism as shown in figure. If the coefficient of friction is sufficiently high so that the prism does not slide before topping, the minimum force required to topple the prism is

A block of mass m = 2kg is accelerating by a force F = 20N applied on a smooth light pulley as shown in the figure. If the coefficient of kinetic friction between the block and the surface is mu=0.3 , find its acceleration.

A block of mass m=4kg is placed oner a rough inclined plane as shown in figure. The coefficient of friction between the block and the plane is mu=0.5 . A force F=10N is applied on the block at an angle of 30^(@) .

Two blocks of masses m and 2 m are placed one over the other as shown in figure.The coefficient of friction between m and 2m is mu and between 2m and ground is (mu)/(3) . If a horizontal force F is applied on upper block and T is tension developed in string, then choose the incorrect alternative.

In the arrangement shown in figure, coefficient of friction between the two blocks is mu=1//2 . The force of friction acting between
