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
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.
