An open-ended U-tube of uniform cross-sectional area contains water (density 1.0 gram/centimeter3) standing initially 20 centimeters from the bottom in each arm. An immiscible liquid of density 4.0 grams/ centimeter3 is added to one arm until a layer 5 centimeters high forms, as shown in the figure above. What is the ratio h2 /h1 of the heights of the liquid in the two arms?
