Hooke's Law in Physics States That If a Spring at Rest

Short Answer

Hooke's Law in physics states that if a spring at rest (equilibrium position ) has a weight attached to it, then the distance the spring stretches is directly proportional to the force (weight).
F = kx
where F is the force in Newtons(N), x is the distance stretched in meters (m), and k is the spring constant (N/m).
A force of 300 N will stretch the spring 20 cm. How much force is required to stretch the spring
