Question
A glass U-tube is such that the diameter of one limb is 3.0 mm and that of the other is 6.00 mm. The tube is inverted vertically with the open ends below the surface of the water in a beaker. What is the difference between the heights to which water rises in the two limbs? The surface tension of water is 0.07 nm−1. Assume that the angle of contact between water and glass is 0∘
