A cylindrical iceberg of height H floats in sea water. The top of the iceberg is at height h above the surface of the water. The density of ice is ρ_i and the density of sea water is ρ_w. What is the height h of the iceberg above the sea water?

1. A\left(1 - \dfrac{\rho_i}{\rho_w}\right) H
2. B\left(\dfrac{\rho_i}{\rho_w} - 1\right) H
3. C\dfrac{\rho_w}{\rho_i} H
4. D\dfrac{\rho_i}{\rho_w} H
