1.	These questions consist two statements each, printed as Assertion and reason, while answering these question you are required to choose any one of the following four responsis: (a) If both the assertion and reason are true and reason is a true explanation of the assertion. (b) If both the assertion and reason are true but the reason is not the correct explanation of assertion. (c ) If the assertion is true but reason is false. (d) If both the assertion and reason are false. Q. Assertion: Bulk modulus of elasticity (K) represents incompressibility of the material. Reason: Bulk modulus of elasticity is proportional to change in pressure.
Answer» Correct Answer - A Bulk modulus of elasticity measures how good the body is to regain its original volume on being compressed. Therefore, it represents incompressibility of the material, `K=(-PV)/(triangleV)` where `P` is increase in pressure, `triangleV` is change in volume.
