A container is filled with liquid. At a depth of 60 cm it exerts a pressure of 2000 Pa.
We need to find the density of the liquid.
The pressure exerted by liquid at a depth is given by the formula as follows :
h = 60 cm = 0.6 m
g is acceleration due to gravity
Putting all the values,
So, the density of the liquid is .
