Final answer:
The normal force exerted by the floor on a person standing on it is equal to the person's weight.
Step-by-step explanation:
In physics, the normal force is the force exerted by a surface to support the weight of an object resting on it. When you stand on a floor, the normal force exerted by the floor on you is equal in magnitude but opposite in direction to your weight. This means that the normal force is equal to your weight.
