Two narrow bores of diameters 3.0 mm and 6.0 mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3×10–2Nm–1. Take the angle of contact to be zero and density of water to be 1.0×103kgm–3(g=9.8ms–2). |
