Question

A block weighing 10n rests on a horizontal surface the coefficient of static friction between the block and the surface is 0.4 and the coefficient of sliding friction is 0.2 if a horizontal force of 5n is applied on a block the magnitude of the frictional force acting on the block is

Answer 1

Answer:

Explanation:

Answer:

Explanation:

Answer:

Since there is no applied force, there is no force of friction. (b) Force of friction is a self-adjusting force. During the stationary state, it is equal to the applied force. Hence the magnitude of frictional force on it is 10 N.
