When a glass capillary tube of the radius$0.015 \mathrm{cm}$is dipped in water, the water rises to a height of$15 \mathrm{cm}$within it. Assuming the contact angle between water and glass to be$0°$, the surface tension of water is$[{\mathrm{\rho }}_{\mathrm{w}\mathrm{a}\mathrm{t}\mathrm{e}\mathrm{r}\mathrm{ }}=1000 \mathrm{k}\mathrm{g}\mathrm{ }{\mathrm{m}}^{-3},\mathrm{ }\mathrm{g}=9.81\mathrm{ }\mathrm{m} {\mathrm{s}}^{-2}]$
