What normal force does a horizontal table exert on a 3.5 kg book that sits at rest?

34.3N

Explanation:

The normal force, denoted by F(N), is the force exerted on an object by a surface. The normal force in this case is acting in an opposite manner but equal magnitude to the force of gravity.

F(N) = Fg

Where;

F(N) = Normal force

Fg = gravitational force

Fg = mg

Where;

m = mass (kg)

g = acceleration due to gravity

F(N) = mg

F(N) = 3.5kg × 9.8m/s²

F(N) = 34.3N

Hence, the normal force acting on the object is 34.3N.
