NEET Physics Bulk Modulus MCQ Question
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?
B = –p/(ΔV/V)
B = p/(ΔV/V)
B = –(ΔV/V)/p
B = p/ΔV
Correct Answer
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.
