Physics-Bulk Modulus
NEET Physics Bulk Modulus MCQ Question
Type: MCQ-diagram based-Easy-Class 11
A cube of material is shown subjected to a uniform increase in external pressure, resulting in a decrease in its volume. Which of the following expressions correctly represents the bulk modulus of the material?
A
B = –p/(ΔV/V)
B
B = p/(ΔV/V)
C
B = –(ΔV/V)/p
D
B = p/ΔV
Correct Answer
Option A
Detailed Explanation
The bulk modulus is defined as the ratio of hydraulic stress (pressure) to the corresponding hydraulic strain (volume strain), given by B = –p/(ΔV/V) as per the NCERT context.
