An astronaut landed on a far away planet that has a sea of water. to determine the gravitational acceleration on the planet's surface, the astronaut lowered a pressure gauge into the sea to a depth of 12.3 m. if the gauge pressure is measured to be 1.1 atm, what is the gravitational acceleration on the planet's surface? use 1000 kg/m3 as the mass density of water.

To solve this problem it is necessary to apply the concepts related to hydrostatic pressure or pressure due to a fluid.

Mathematically this pressure is given under the formula

Where,

= Density

h = Height

g = Gravitational acceleration

Rearranging in terms of g

our values are given as

Replacing we have

Therefore the gravitational acceleration on the planet's surface is (Almost the gravity of the Earth)
