(b) a lake is 5.0m deep the density of the water is 1000kg/m3 (i) calculate the pressure at the bottom of the lake due to the depth of water And the one under it I would appreciate the help thanks !

Given :

Density of the water, .

Depth of lake, d = 5 m.

To Find :

The pressure at the bottom of the lake due to the depth of water.

Solution :

We know, hydrostatic pressure is given by :

( Here,  g is acceleration due to gravity, g = 10 m/s².

Putting all values in above equation, we get :

Hence, this is the required solution.
