A cylindrical tank having cross-sectional area `A = 0.5 m^(2)` is filled with two liquids of density `rho_(1) = 900/ kg /m^-3` and `rho_2 = 600 kg/m^-3`, to a height `h = 60 cm` each as shown in the figure. A small hole having area `a = 5 cm^2` is made in right vertical wall at a height `y = 20 cm` from the bottom. A horizontal force `F` is applied on the tank to keep it in static equilibrium. The tank is lying on a horizontal surface. Neglect mass of the cylindrical tank in comparison to mass of the liquids (`ake `g = 10 ms^(-2)`).
