A tank, with a square base of area 1 .0 m^(2)is divided by a vertical partition has a small hinged door of aren 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 m. Compute the force necessary to keep the door closed

1.	A tank, with a square base of area 1 .0 m^(2)is divided by a vertical partition has a small hinged door of aren 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 m. Compute the force necessary to keep the door closed
Answer» Solution :Force ` = ( 4xx 1.7 xx 10 ^(3) xx 9.8 - 4 xx 10 ^(3) xx 9.8 ) xx 20 xx 10 ^(-4)= 54. 88 N`
