A hemispherical portion of radius -R is removed from the bottom of a cylinder of radius R. The volume of remaining cylinder is V and its mass is M. It is suspended by a string in a liquid of density $\rho$, where it stays vertical. The upper surface of the cylinder is at a depth h below the liquid surface. The force on the bottom of the cylinder by the liquid is 

• A

  M g

• B

  $\mathrm{Mg}-\mathrm{V\rho g}$

• C

  $\mathrm{Mg}+{\mathrm{\pi R}}^2\mathrm{h\rho g}$

• D

  $\mathrm{\rho g}\left(\mathrm{V}+{\mathrm{\pi R}}^2\mathrm{h}\right)$
