Question

The pressure exerted by a liquid at depth $h$ is given by:

• A. $\frac{h}{dg}$
• B. $hdg$
• C. $\frac{h}{d}$
• D. $hg$

Answer 1

Answer: (B)

$hdg$

Answer is B.
The pressure exerted by a liquid at a point depends on its vertical depth and density of the liquid only. It is independent of the shape of the container. The pressure at the bottom of the three vessels of different shapes containing the same liquid acts equally in all directions.
Thus, the pressure exerted by the liquid of height $h$ is given as P=hdg, where $h$ is the height, $d$ is the density and $g$ is the acceleration due to gravity.
