Two liquids of densities ρ_1 and ρ_2(ρ_2=2 ρ_1) are filled up behind a square wall of side 10 m as shown in figure. Each liquid has a height of 5 m.…
Two liquids of densities $\displaystyle \rho_1$ and $\displaystyle \rho_2\left(\rho_2=2 \rho_1\right)$ are filled up behind a square wall of side $\displaystyle 10$ m as shown in figure. Each liquid has a height of $\displaystyle 5$ m. The ratio of the forces due to these liquids exerted on upper part MN to that at the lower part NO is (Assume that the liquids are not mixing) :Official answer
