Question

A person applies a force of 20 N horizontally on a cube of weight 30 N, but it does not move at all. Identify the type of frictional force and also draw its free body diagram (FBD).

Open in App

Solution

As the block is not moving, the muscular force of 20 N is balanced out by static friction between the cube and the surface.
So free body diagram will be as follows.
