Two tubes of same length and diameters 4 mm and 8 mm are joined together to form a U-shaped tube open at both the ends. If the U-tube contains water, then the difference between the levels of water in the two limbs of the tube is
(Surface Tension of water at the temperature of experiment is 7.3 × 10−2Nm−1. angle of contact = 0°. density of water = 1.0 × 103 kg m−3 and acceleration due to gravity =10 ms−2)
