ANSWER:
The answer is given in the step by step
Explanation:
Normal force is called the force exerted by a surface on the body that is resting on it. The normal force has the opposite sense, but the same direction and magnitude, as the force exerted by the body itself on the surface in question. Also, the normal force is the force that surfaces exert to prevent solid objects from passing through each other. The normal force is a contact force. If two surfaces are not in contact, they cannot exert normal force on each other.
