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
