A vertical U tube of uniform cross section contains mercury in both of its arms. A glycerin (d=1.3g/cm^3) column of length 10cm is introduced into one of the arms. Oil of density 0.8g/cm^3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6g/cm^3.
