A vertical manometer contains a nonvolatile oil. When one arm of the manometer is open to the atmosphere and the other is connected to a sealed chamber, the oil column in the chamber’s arm rises 28cm above the atmospheric arm. An independent sensor shows that the chamber’s pressure is 3.2×103Pa greater than atmospheric pressure. Using g=9.8m/s2, determine the density of the oil.
(a) 6.0×102kg/m3
(b) 1.2×103kg/m3
(c) 2.3×103kg/m3
(d) 3.2×102kg/m3
