Two liquids of densities $\rho_{1}$ and $\rho_{2}\left(\rho_{2}=2 \rho_{1}\right)$ are filled up behind a square wall of side $10\; \mathrm{m}$ as shown in figure. Each liquid has a height of $5 \;\mathrm{m} .$ The ratio of the forces due to these liquids exerted on upper part $MN$ to that at the lower pait $NO$ is (Assume that the liquids are not mixing)
