Objective Question & Answer

The pressure at a depth hhh in a liquid is given by

P=ρgh

(where ρ is the density of the liquid and g is acceleration due to gravity).

This pressure depends only on the vertical height of the liquid column above the point and is

independent of the shape or cross-sectional area of the container (hydrostatic paradox).

In the given figure, all three containers are filled with water to the same height. Therefore the

pressure at the bottom of each container is the same:

P₁=P₂=P₃
