Nellie's weight and normal force usually have the same magnitude when she stands on a
A)horizontal surface.
B)inclined surface.
C)either a horizontal or inclined surface.

Question

Quizplus · Accepted Answer

The normal force is the force exerted perpendicular to the surface on which the object rests. On a horizontal surface, the normal force is equal in magnitude to the weight of the object, as both act in opposite directions along the same line. However, on an inclined surface, the normal force is less than the weight of the object as the weight has a component along the surface. Therefore, the correct choice is A).
