.When any body float on the surface of liquid then weight of body $=$ weight of displaced liquid

by the body.

$\mathrm{V} \rho g=\mathrm{V}^{\prime} \rho_{l} g$ (where $\mathrm{V}=$ volume of body)

$\mathrm{V}^{\prime}=$ volume of partially part of immerged in liquid

$=$ volume of displaced liquid

$\rho=$ Density of body

$\rho_{l}=$ Density of liquid

$\therefore \frac{\mathrm{V}^{\prime}}{\mathrm{V}}=\frac{\rho}{\rho^{\prime}}=\frac{\text { Volume of immerged part of body }}{\text { Total volume of body }}$

$=\frac{\text { Density of body }}{\text { Density of liquid }}$
