Answer:
The extension is directly proportional to the force exerted by the weight on the spring.
Step-by-step explanation:
When the weight is suspended to a spring , the spring is extended through a length say x cm . This displacement is directly proportional to the force exerted on the spring equal to its weight.
Mathematically
F ∝ -x
F= -kx
where x is the displacement of the spring and k is the spring's constant whose value depends on the stiffness of the spring. F is the force exerted by the weight on the spring.
If more weight is added the extension will be greater . If less weight / force is applied the extension in the spring will be less.
