Three liquids having densities ρ1 , ρ2 , ρ3 are filled in a U-tube. Length of each liquid column is equal to I, ρ1>ρ2>ρ3 and liquids remain at rest (relative to the tube) in the position shown in the figure. It is possible that Three liquids having densities ρ1 ρ1>ρ2>ρ3 and liquids remain at rest [...]
