A submarine is stranded on the bottom of the ocean with its hatch 25 m below the surface. In this problem, assume the density of the sea water is 1.03 x 103kg/m3. Calculate the force, in newtons, needed to open the hatch from the inside, given it is circular and -0.15m in diameter. The air pressure inside the submarine is 1.00 atm.
