Hookes Laws is used in the determination of
Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. When the elastic materials are stretched, the atoms and molecules deform until stress is been applied and when the stress is removed they return to their initial state. Hooke's law is used as a fundamental principle behind manometer, spring scale, balance wheel of the clock. S o it is used in the determination of weight of the body.
