In hooke’s law, what does the x represent? a. the thickness of the spring b. the length of the spring c. the displacement of the spring d. the distance from stretched to compressed e. the equilibrium distance

  C

X = Displacement of the spring

Hooke's law: It states that the applied force F is proportional to the  displacement of spring .

            F ∝ x

            Where, x = displacement of spring in meters

                         F = force, measured in Newtons

In another words The force F is equal to the constant K times the disparagement.

            F = k.x

            Where k is constant and it depends on elastic material.

            Spring has restorative force.  

If the spring moves in opposite direction then,

           F = - k.x

A negative sign indicates that the spring resists and force is to the left. The compression of the spring is greater than the restoring force.  

   Example: A mass 'm' stretches a spring at a displacement x.
