The density of a liquid is

\rho

at the surface. The bulk modulus of the liquid is B. The increase

\Delta \rho

in the density of the liquid at a depth

h

from the surface is (with

\Delta \rho \ll \rho

)

Options

A $\Delta \rho=\frac{\rho^2 g h}{B}$
B $\Delta \rho=\frac{\rho g h}{B}$
C $\Delta \rho=\frac{\rho^2 g h}{2 B}$
D $\Delta \rho=\frac{2 \rho^2 g h}{B}$

Correct answer

A. $\Delta \rho=\frac{\rho^2 g h}{B}$

Step-by-step solution
