Two narrow bores of diameters of 3 mm and 6 mm are joined together to form U-shaped tube open at both ends. If the U-tube contains water, what is the difference in levels in two limbs of the tube ? Surface tension of a water at the temperature of experiment is 7.3 x 10-² N/m. Take the angle of contact to be zero and density of water to be 1 x 10° kg.
