A boat has a porthole window, of area 0.00849 m^2, 6.25 m below the surface. The density of sea water is 1027 kg/m^3. The air inside the boat is at 1 atm. What is the net force on the window?

outward.

Explanation:

= Density of water =

g = Acceleration due to gravity =

h = Height of the water = 6.25 m

A = Area of the window =

= Internal pressure of the boat =

Pressure by the water on the window

Net pressure on the window

Force is given by

Net force on the window is outward.
