A capillary tube made of glass of radius0.15 mm is dipped vertically in a beaker filledwith methylene iodide (surfacetension =0.05 Nm−1, density =667 kg m−3)which rises to height h in the tube. It is observedthat the two tangents drawn from liquid-glassinterfaces (from opp. sides of the capillary)make an angle of 60° with one another. Then h is close to ( g=10 ms−2)
