Question

The density of ice is $917kg{m}^{-3}$. What fraction of the volume of a piece of ice will be above water, when floating in fresh water?

• A. 0.06
• B. 0.083
• C. 0.038
• D. 0.068

Answer 1

The correct option is B 0.083

Acc. to Archemedes principal

${\rho }_{1}vg=P_2{v}_{i}g$

$\frac{v_i}{v}=\frac{f_1}{{\rho }_2}=\frac{917}{1000}=0.917$

Fraction outside water $=0.083$

Answer $\left(B\right)0.083$
