Question

Assertion: For an ideal liquid- i) Bulk modulus = ∞ ii) Shear modulus = 0. Reason: An ideal liquid is incompressible and has no viscosity

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.
