A hemispherical portion of radius $R$ is removed from the bottom of a cylinder of radius $R$. The volume of the remaining cylinder is $V$ and mass $M$. It is suspended by a string in a liquid of density $\rho$, where it stays vertical. The upper surface of cylinder is at a depth $h$ below the liquid surface. The force on the bottom of the cylinder by the liquid is
  • A$\rho g (V + \pi R^2)$
  • B$Mg$
  • C$Mg - V \rho g$
  • D$\rho g (V + \pi R^2 h)$
