Capillary Action

On dipping one end of a capillary in liquid and inclining the capillary at an angles 30^o and 60^​o with the vertical, the lengths of liquid columns in it are found to be $l_1$ and $l_2$ respectively. The ratio of $l_1$ and $l_2$ is

Write down applications of the capillarity.

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 $[{\mathrm{\rho }}_{\mathrm{w}\mathrm{a}\mathrm{t}\mathrm{e}\mathrm{r}\mathrm{ }}=1000 \mathrm{k}\mathrm{g}\mathrm{ }{\mathrm{m}}^{-3},\mathrm{ }\mathrm{g}=9.81\mathrm{ }\mathrm{m} {\mathrm{s}}^{-2}]$
