Physics - Fluid Question with Solution | TestHub

A capillary tube made of glass of radius$0.15 \mathrm{mm}$is dipped vertically in a beaker filled with methylene iodide (surface tension$= 0.05 \mathrm{N} {\mathrm{m}}^{-1}$, density$= 667 \mathrm{kg} {\mathrm{m}}^{-3}$) which rises to height$\mathrm{h}$in the tube. It is observed that the two tangents drawn from observed that the two tangents drawn from liquid-glass interfaces (from opp. sides of the capillary) make an angle of$60º$with one another. Then$\mathrm{h}$is close to ($\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}$)
