You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 140kPa , and the depth of the water will be 13.8m . The pressure of the air in the building outside the tank will be 87.0kPa
Part A
Find the net downward force on the tank's flat bottom, of area 1.90m2 , exerted by the water and air inside the tank and the air outside the tank.
Express your answer numerically in Newtons, to three significant figures.
