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 hasa 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.
