1. The problem statement, all variables and given/known data A submarine is operating at 100 m below the surface of the ocean. If the air inside the submarine is maintained at a pressure of 1 atmosphere, what is the magnitude of the force that acts on the rectangular hatch 2.0 x 1.0 m on the deck of the submarine? 2. Relevant equations Force = Pressure* Area Pressure = density*gravity*height ? 3. The attempt at a solution If atmospheric pressure is 1.013 x 10^5 Pa and Area of hatch = width * height Then, Area = 2*1 = 2 m^2 Force = (1.013 x 10^5 Pa)(2 m^2) = 202600 This doesn't seem right to me and I know I'm missing something. I just can't seem to put my finger on it. Please help.
