Physics-Bulk Modulus

NEET Physics Bulk Modulus Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): The bulk modulus of a material is always positive. | Reason (R): The bulk modulus is the ratio of hydraulic stress to hydraulic strain, where a decrease in volume is indicated by a negative change in volume.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The assertion and reason are both true as the bulk modulus is defined as the ratio of hydraulic stress to volume strain, and is always positive because an increase in pressure results in a decrease in volume, which is denoted by a negative volume change.
