STANDARD Physics Bulk Modulus MCQ Question

Type: MCQ-numerical-Medium-Class 11

How much pressure should be applied on a litre of water if it is to be compressed by 0.1%? (Bulk modulus of water = 2100 MPa)

A

2100 kPa

B

210 kPa

C

2100 MPa

D

210 MPa

Correct Answer

Option A

Detailed Explanation

The bulk modulus formula is B = P / (ΔV/V). Given B = 2100 MPa and ΔV/V = 0.1/100 = 1×10⁻³, we find P = B × (ΔV/V) = 2100 × 10⁶ Pa × 1×10⁻³ = 2100 × 10³ Pa = 2100 kPa.
