A tank with a square base of area `1.0 m^2` is divided by a vertical position in the middle. The bottom of the partition has a small hinged door of area `20 cm^2` The tank is filled with water in one compartment, and an acid (of relative density 1.7) in the other. both to the height of 4.0 cm compute the force necessary to keep the door close.
