Question

Assertion: Young's modulus, Shear modulus and Bulk modulus are used to describe the elastic behaviour of objects as they respond to deforming forces that act on them. Reason: Young's modulus and Shear modulus are relevant only for solids. Bulk modulus is relevant for solids, liquid, and gases.

Assertion: Bulk modulus of elasticity (K) represents incompressibility of the material. Reason: Bulk modulus of elasticity is proportional to change in pressure.

A uniform cube is subjected to volume compression. If each side is decreased by 1%, then Calculate bulk strain produced in cube.

A ball falling in a lake of depth 200 m shows 0.1% decrease in its volume at the bottom. What is the bulk modulus of the material of the ball?
