The vessel shown in the fig has two sections of areas of cross-section $A_1$ and $A_2$.  A liquid of density $\rho$ fills both the sections, up to height h in each. Neglect atmospheric pressure:

The pressure at the base of the vessel is  $2h\rho g$

The force exerted by the liquid on the base of the vessel is  $2h\rho g{A}_2$

The weight of the liquid is less than $2h\rho g{A}_2$

The horizontal walls of the vessel at the level X exert a downward force  $h\rho g(A_2-A_1)$ on the liquid
