361028 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:
