1. The problem statement, all variables and given/known data I have a cylindrical water tank of mars, where acc. due to gravity= 3.71 The pressure at the surface of the water is 110 kPa, and the depth of the water is 14.5 m The pressure of the air outside the tank is 91 kPa Find the net downward force on the tanks flat bottom of area 2.4 m^2, exerted by the water and air inside the tank and the air outside the tank 2. Relevant equations p= F/A 3. The attempt at a solution alright, I found the downward force to be 3.93x10^5 N upward force to be 2.18x10^5 I thought the sum of these forces would give me the net forces but I must've been mistaken because the answer was wrong.
