Answer

Explanation:

Step1: Understand dynamic equilibrium

In dynamic equilibrium, the net force on the object is zero.

Step2: Analyze forces

The applied force is 20 newtons. For the net - force to be zero, the frictional force must balance the applied force.

Step3: Determine frictional force

The frictional force has a magnitude equal to the applied force (20 newtons) and acts in the opposite direction to oppose the motion caused by the applied force.

Answer:

B. 20 newtons opposite to the direction of the applied force
