Question : 142 of 200

Marks: +1, -0

The volume of a wooden block, of specific gravity of 0.5, is 0.1

m^3

. The volume of the block immersed in water when floating is:

Solution:

Given:
S.G.

=\ρ_{b} \/ \ρ_{w}=0.5, \ρ_{b}=500

and

{V}=0.1 {m}^{3}

\ρ_{b} g V=\ρ_{f} g V_{f d}

\∴500 \×9.81 \×0.1

=1000 \×9.81 \×V_{f d}

\∴V_{f d}=0.05 {m}^{3}
