For a constant hydraulic stress P on an object with bulk modulus (B), the fractional change in the volume of object will be

$\frac{P}{B}$

$\frac{B}{P}$

$\sqrt{\frac{P}{B}}$

${(\frac{B}{P})}^{2}$

Solution

$\frac{P}{B}$

Bulk modulus:- It is the ratio of hydraulic strain to the corresponding hydraulic strain is called Bulk modulus.

It is denoted by symbol B

B = $\frac{- ∆ P}{\frac{∆ V}{V}}$

⇒ $|\frac{∆ V}{V}| = \frac{P}{B}$
