NEET 2017 Physics Elasticity MCQ Question

Type: MCQ-numerical-Medium-Class 11

The bulk modulus of a spherical object is ‘B’. If it is subjected to uniform pressure ‘P’, the fractional decrease in radius is

A

P/B

B

3P/4B

C

P/3B

D

B/3P

Correct Answer

Option C

Detailed Explanation

The fractional change in volume is given by ΔV/V = -P/B. For a sphere, Δr/r = ΔV/3V, leading to the fractional decrease in radius as P/3B.
