Fluid statics

Question

The fraction of a floating object of volume $V_{o} and density d_{o}$ above the surface of a liquid of density d will be

Moderate

A

$\frac{d_{o}}{d}$
B

$\frac{{dd}_{o}}{d + d_{o}}$
C

$\frac{d - d_{o}}{d}$
D

$\frac{{dd}_{0}}{d - d_{0}}$

Solution

For the floatation $V_{o} d_{o} g = V_{in} dg \Rightarrow V_{in} = V_{o} \frac{d_{o}}{d}$
$V_{out} = V_{o} - V_{in} = V_{o} - V_{o} \frac{d_{o}}{d} = V_{o} [\frac{d - d_{o}}{d}]$
$\frac{V_{out}}{V_{o}} = \frac{d - d_{0}}{d}$
