    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 is 'M'. It is suspended by a string in a liquid of density 'ρ\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 liquid is
