Three identical vessels `A, B` and `C` contain same quantity of liquid. In each vessel balls of different densities but same masses are placed. In vessel `A`, the ball is partly submerged, in vessel `B`, the ball is completely submerged but floating and in vessel `C`, the ball has sunk to the base. If `F_(A), F_(B)` and `F_(C)` are the total forces acting on the base of vessels `A, B` and `C`, respectively, then
