Question

The bulk modulus of a liquid is 3 × 1010 Nm-2. The pressure required to reduce the volume of liquid by 2% is

• A. 3 × 108 Nm-2
• B. 9 × 108 Nm-2
• C. 6 × 108 Nm-2
• D. 12 × 108 Nm-2

Answer 1

Answer: (C)

6 × 108 Nm-2

Answer 2

$∵ B= [\frac{ΔP}{(-\frac{Δv}{v})}]$
⇒$ΔP=3×10^{10}×(0.02)$
= 6 × 108 N/m2

The correct option is (C): 6 × 108 Nm–2
