Question

Can a normal force be horizontal?

Answer 1

Answer:

Yes it can be

Explanation:

Since the normal force is a reactive force, its magnitude is independent of the nature of the force causing it. ... Thus, in the situation of a horizontal object, the normal force is simple: it is merely equal in magnitude and opposite in direction to all forces applied to the surface.

and also for example

When an object is in contact with a surface the normal force acts perpendicular to the surface and is equal to the component of the object's weight perpendicular to the surface. So on a flat table (horizontal) normal force is vertical = object's weight (mg).

Answer 2

Answer:

since the normal force is a reactive force, its magnitude is independent of the nature of the force causing it,thus, in the situation of horizontal object,the normal force is simple,it is merely equal in magnitude and opposite in direction to all forces applied to the surface.
