A tank with a square base of area

1.0\,{{\text{m}}^2}

is divided by a vertical partition in the middle. The bottom of the partition has a small hinzed door of area

20\,{\text{c}}{{\text{m}}^2}.

The tank is filled with water in one compartment and an acid of relative density 1.7 in the other, both to a height of 4m. The force acting on the door is

\left( {g = 1\,{\text{mn}}{{\text{s}}^{ - 2}}} \right)

View answer and explanation

Correct option: B

56 N

Option B (56 N) is correct because the force is calculated by considering the pressure difference due to the different densities of water and acid.
