Answer:
It is not a universal principle.Beyond the elastic limit of the material, the law is not applicable.It is applicable only for solids
Formula
Fs= -kx
Hooke's law also referred to as the "law of elasticity" which was discovered by an English scientist named Robert Hooke in the year 1660.
Hooke's law basically states that “when an object has a relatively small deformation the size of the deformation is directly proportional to the deforming load or force.”
Explanation
Example:
When inflating a Balloon
A balloon is elastic in nature. When the air molecules are blown in it, it expands. Similarly, when it is evacuated, it shrinks in size. The expansion and compression of the balloon depend on the force with which the air is pressed into it; therefore, it works on the basis of Hooke's law.
