Question

A block of wood floats in water with $\frac{2}{3}$ of its volume submerged. Its relative density is equal to :

• A. $\frac{1}{3}$
• B. $\frac{2}{3}$
• C. $\frac{4}{3}$
• D. $\frac{1}{9}$

Answer 1

The correct option is B $\frac{2}{3}$

$Relativedensity=\frac{Volumeofbodysubmerged}{totalvolumeofbody}$

$=\frac{2/3V_0}{V_0}$

$=2/3$
