What will be the restoring force if a spring with a spring constant of 45 newtons per meter is pulled 0.03 meters in the downward direction?

To calculate for the force in a spring, we use Hooke's Law which relates force and the displacement of the spring. It is said that the force is directly proportional to the displacement. So, it will have the equation F = kx where k is a constant and it is the spring constant.

F = kx
F = 45 N/m (0.03)
F = 1.35 N
