The bulk modulus of a liquid is 3 $\times$ 10¹⁰ Nm^$-$2. The pressure required to reduce the volume of liquid by 2% is :

A 3 $\times$ 108 Nm$-$2
B 9 $\times$ 108 Nm$-$2
C 6 $\times$ 108 Nm$-$2 Correct answer
D 12 $\times$ 108 Nm$-$2

Solution

$\because$ $B = {{\Delta P} \over {\left( { - {{\Delta V} \over V}} \right)}}$ $\Rightarrow \Delta P = 3 \times {10^{10}} \times (0.02)$ $= 6 \times {10^8}$ N/m2
