A cylindrical tank having a cross-sectional area $A=0.5m^2$ is filled with two liquids of density ${\rho }_1=900kg{m}^{-3}and{\rho }_2=600kg{m}^{-3}$ to a height h = 60 cm each as shown in the figure. A small hole having an area $a=5c{m}^2$ is made in the right vertical wall at a height y = 20 cm from the bottom. A horizontal force F is applied to the tank to keep it in static equilibrium. The tank is lying on a horizontal surface. Neglect the mass of the cylindrical tank in comparison to the mass of the liquids (take $g=10m{s}^{-2}$ , Neglect flow velocity inside the tank)
