The normal force is 500 N. The applied force is 20 N.
Coefficient of friction is 0.2. What is the frictional force between the surfaces?

The maximum frictional force will be μ N = 0.2*500 = 100N.

The applied force is only 20N, less than 100N.
Hence the frictional force will be only 20 N

======================================

Givens
Normal force, Fn = 500 N
Applied force, Fa = 20 N
coefficient of friction, μ = 0.2
Frictional force, Ff = ?

Frictional force, as you should know, is simply equal to the product of coefficient of friction and the normal force. In mathematical terms, Ff = μFn.

Since the normal force and the coefficient of friction is already given to you, you can solve for frictional force using the formula provided above.

Ff = μFn
Ff = (0.2)(500)
Ff = 100 N

Note: Since frictional force is greater than the applied force, the object wouldn't actually move at all! (Or if it's already in motion, then it is moving at a constant velocity)
