On an inclined plane of inclination angle `30^(@)`, a block is placed. It is observed that the force to drage the block along the plane upwards is smaller than the force required to lift it. The maximum value of coefficient of friction is .

A block of weight w rests on a horizontal plane. A force P inclined at an angle theta to the plane is applied to the block until it is on the of motion. Find the value of coefficient of friction.

A block is placed on an inclined plane. The angle of inclination of the plane is such that the block slides down the plane at a constant speed. The coefficient of kinetic friction is
