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 its mass 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

Options

A. `Mg`
B. `Mg - V rho g `
C. `Mg + pi R^(2) h rho g`
D. `rho g (V + pi R^(2) h)`

Answer
