An iceberg of density $900$ kg m$^{-3}$ floats in sea water of density $1030$ kg m$^{-3}$. The fraction of its volume above the water surface is about
Answer: (D) $12.6\%$
Concept. Floating: fraction submerged $= \dfrac{\rho_{\text{body}}}{\rho_{\text{liquid}}}$.
Step 1. Submerged. $\dfrac{900}{1030} \approx 0.874$.
Step 2. Above water. $1 - 0.874 = 12.6\%$.
Answer. $12.6\%$ (Option D).
