In the U-tube belоw, the density оf the fluid thаt fills the upper pаrt оf the left-hаnd portion is ρA=831 kg/m3{"version":"1.1","math":"ρA=831 kg/m3"}. The density of the fluid that fills the right-hand portion, ρB{"version":"1.1","math":"ρB"}, is unknown. Both ends are open to the atmosphere. The heights of three different sections are labeled on the diagram. The lowest section has height h3 = 5.0 cm. The middle section has height h2 = 3.0 cm. The upper section has height h1 = 7.0 cm. The density of the fluid on the right side of the U-tube is most nearly
