Derive the expression for the pressure exerted by the gas on the seal as a function of pressure Pa of the outside air, the force F exerted by Earth on the water, the area A of the water seal, and angle θ . Note that surface tension keeps the water-gas interfaces essentially perpendicular to the tube. Express your answer in terms of the variables Pa , F, A, and θ.
