STANDARD Physics Bulk Modulus MCQ Question

Type: MCQ-numerical-Medium-Class 11

The volume change of a solid copper cube 10 cm on an edge, when subjected to a pressure of 7 MPa is (Bulk modulus of copper = 140 GPa)

A

5 × 10⁻² cm³

B

10 × 10⁻² cm³

C

15 × 10⁻² cm³

D

20 × 10⁻² cm³

Correct Answer

Option A

Detailed Explanation

Using the formula ΔV = (P/B) × V, where P = 7 × 10⁶ Pa, B = 140 × 10⁹ Pa, and V = (10 × 10⁻² m)³, we find ΔV = 5 × 10⁻⁸ m³ = 5 × 10⁻² cm³.
