The vessel shown in the figure has two sections. The lower part is a rectangular vessel with area of cross-section $A$ and height $h$. The upper part is a conical vessel of height $h$ with base area $‘A’$ and top area $‘a’$ and the walls of the vessel are inclined at an angle $30^o$ with the vertical.A liquid of density $\rho$ fills both the sections upto a height $2h$. Neglecting atmospheric pressure.

- A
The force $F $ exerted by the liquid on the base of the vessel is $2h\rho g$$\frac{{(A + a)}}{2}$
- B
the pressure $P $ at the base of the vessel is $2h\rho g $$\frac{A}{a}$
- C
the weight of the liquid $W $ is greater than the force exerted by the liquid on the base
- D
the walls of the vessel exert a downward force $(F-W)$ on the liquid.
