Question
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° with the vertical. A liquid of density r fills both the sections upto a height 2h. Neglecting atmospheric pressure
- The force F exerted by the liquid on the base of the vessel is 2hrg
- the pressure P at the base of the vessel is 2hrg
- the weight of the liquid W is greater than the force exerted by the liquid on the base
- the walls of the vessel exert a downward force (F–W) on the liquid.
The correct answer is: the walls of the vessel exert a downward force (F–W) on the liquid.
