Density and pressure — practice question

A cylindrical iceberg with height $H$ is floating in sea water. The upper end of the iceberg lies at a height $h$ above the water surface. The density of ice is $\rho_i$ and the density of sea water is $\rho_w$. Determine the height $h$ of the iceberg above the sea water.

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