Question

Write an expression for the pressure at a point inside a liquid. Explain the meaning of the symbols used.

Answer 1

$P=P_o+\rho gh$

Here, $P=\text{Pressure at the given point}{P}_o=\text{Pressure at the free surface of the liquid}\rho =\text{Density of the liquid}g=\text{Acceleration due to gravity}h=\text{Depth below the free surface}$
