NEET Physics Bulk Modulus Assertion Reason Question
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.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
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.
