Question

A lake is 5.0 m deep. The density of the water is 1000 kg / m3
.
(i) Calculate the pressure at the bottom of the lake due to this depth of water

Answer 1

Explanation:

Correct option is

A

60000

Hydrostatic pressure = ϱgh

given  ϱ=103kg/m31g=10ms−2,h=6m

Pressure = 103m3kg×10s2m×6

                = 60000 Pa

Answer 2
