In the figure, a solid uniform cube is placed on a horizontal surface. The co-efficient of friction between them is `mu` where `mu lt 1/2`. A variable horizontal force perpendicular to one edge and passing through the midnight of that applied on the cube's upper face. The maximum acceleration with which it can move without toppling is

A solid cube is placed on rough horizontal surface. The coefficient of friction between them is mu, where mu = lt 1//2. A variable horizontal force is applied on the cub's upper face perpendicular to one edge and passing through mid point of that edge. The maximum acceleration with which it can move without toppling is [Acceleration due to gravity 'g'l

A solid cube is placed on a horizontal surface. The coefficient of friction between them is mu=0.25 . A variable horizontal force is applied on the cube’s upper face, perpendicular to one edge and passing through the mid-point of edge, as shown in figure. The maximum acceleration with which it can move without toppling is (take g=10m//s^(2) )

A block of mass m is placed on a rough horizontal surface. The coefficent of friction between them is mu . An external horizontal force is applied to the block and its magnitude is gradually increased. The force exerted by the block on the surface is R.

A block of mass m is placed on a horizontal surface. The coefficient of frication between them is mu . The block has to be moved by applying a single external force on it. The force may be applied in my direciton. The minimum value of this force must be

A heavy uniform chain lies on horizontal table top. If the co-efficient of friction between the chain and the table surface is 0.25, the maximum percentage of the length of the chain that can hang over one edge of the table is

A heavy uniform chain lies on horizontal table top. If the co-efficient of friction between the chain and the table surface is 0.5, the maximum percentage of the length of the chain that can hang over one edge of the table is
