The coefficient of static friction between a wooden block of mass 0.5 kg and a vertical rough wall is 0.2. The magnitude of horizontal force that should be applied on the block to keep it adhere to the wall will be ____N.

The coefficient of static friction between two blocks is 0.5 and the table is smooth. The maximum horizontal force that can be applied to move the blocks together is N. (take g = 10 ms^(-2) )

Consider the arrangement shown in the figure. The coefficient of friction between the two blocks is 0.5 and between the 4 kg block and the horizontal surface is 0.4. If a horizontal force of 12 N is applied on the 4 kg block, the acceleration of the 2 kg block would be

A block of mass 1kg is at rest on a horizontal table. The coeficient of static friction between the block and the table is 0.5 . The magnitude of the force acting upward at an angle of 60^(@) from the horizontal that will just start the block moving is.

A block of mass 2 kg is at rest on a floor . The coefficient of static friction between block and the floor is 0.54. A horizonatl force of 2.8 N is applied to the block . What should be the frictional force between the block and the floor ? ( take , g = 10 m//s^(2) )

In the figure shown, the coefficient of static friction between the block A of mass 20 kg and horizontal table is 0.2. What should be the minimum mass of hanging block just beyond which blocks start moving?

A block weighing 20 N rests on a horizontal surface. The: coefficient of static friction between block and surface is 0.40 and the coefficient of kinetic friction is 0.20. ( a) How large is the friction force exerted on the block? (b) How great will the friction force be if a horizontal force of 5 N is exerted on the block? (c) What is the minimum force that will start the block in motion? (d) What is the minimum force that will keep the block in motion once it has been started? (e) If the horizontal force is 10 N, what is the friction force?

A block of mass 70 kg is kept on a rough horizontal surface and coefficient of static friction between block and surface is 0.4 . A man is trying to pull the block by applying a horizontal force .The net contact force exerted by the surface on the block is F , then:

A block of mass 2kg is held at rest against a rough vertical wall by passing a horizontal (normal) force of 45 N . Coefficient of friction between wall and the block is equal to 0.5. Now a horizontal force of 15 N (tangential to wall) is also applied on the block. Then the block will :
