A block of mass 2kg is placed on the floor. The coefficient of static friction is 0.4. A force F of 2.5N is applied on the block . Calculate the force of friction between the block and the floor.

Two blocks of 2 kg and 1kg are in contact on a frictionless table. If a force of 3N is applied on 2kg block, then the force of contact between the two blocks will be

A block of mass 5 kg rests on a table. 8 N horizontal force is applied to push the block. Find out the force of friction between the block and the table. Given mu_(s)=0.3 "and" mu_(k) =0.2, between the block and the table and g = 10 "m.s"^(-2)

A-block of mass 5 kg. rests on a table. 8 N horizontal force is applied to push the block. Find out the force of friction between the block and the table. Given mu_s = 0.3 and mu_k = 0.2, between the block and the table and g = 10 ms^-2 .

A block of mass 5 kg rests on a table. 8 N horizontal force is applied to push the block. Find out the force of friction between the block and the table. Given, mu_s = 0.3 and mu_k = 0.2 , between the block and the table and g = 10 ms^-2 .

A block of mass 0.1 kg is kept pressed against a wall by applying a force of 5 N horizontally on the block. Coefficient of friction between the block and the wall is 0.5. Friction acting on the block is.

Three blocks of mass 4 kg, 2 kg, 1 kg respectively are in contact on a frictionless table as shown in the figure. If a force of 14 N is applied on the 4 kg block, the contact force between the 4 kg and the 2 kg block will be

A block weighing 250N is pulled over a horizontal plane at a constant velocity up to a distance of 10 m. The coefficient of kinetic friction is 0.2 and the force is applied by a string, attached with the block, inclined at 60^@ with the vertical . Find the work done against friction.
