Question

State two factors on which pressure at a point inside a liquid depends.

Answer 1

There are two factors that affect fluid pressure are:

1. The first factor is the depth of the fluid: the exertion of the pressure by the fluid increases as the depth increases.
2. The second factor is the density of the fluid: there is the exertion of more pressure by denser fluids like water in comparison to lighter fluids like air.

The pressure at a point inside a liquid is given by:
$P=P_0+hdg$
where $P$ is the point where pressure is exerted in the liquid
$P_0$ is the atmospheric pressure
$h$ is the depth of the point below the free surface
$d$ is the density of the liquid
$g$ is the acceleration due to gravity
