Density and pressure — practice question

A cylindrical iceberg with height $H$ is floating in sea water. Its upper end rises to a height $h$ above the water surface. The density of ice is $\rho_i$ and the density of sea water is $\rho_w$. What is the value of $h$ for the iceberg above the sea water?

  • A$\left(1 - \frac{\rho_i}{\rho_w}\right)H$
  • B$\left(\frac{\rho_i}{\rho_w} - 1\right)H$
  • C$\frac{\rho_w}{\rho_i}H$
  • D$\frac{\rho_i}{\rho_w}H$
