Enhancer 7 A U-tube has its limbs of radii 3 mm and 6.0 mm. This tube contains water of surface tension 7.3 x 10-2 N/m. If we take the angle of contact zero and the density of water 10° kg/m3 then the difference of the water in the two limbs of the U-tube is approximately (b) 0.5 mm (c) 3.5 mm (a) 1.5 mm (d) 2.5 mm
