Capillarity and 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

Water rises in a vertical capillary tube upto a height of $2.0 \mathrm{cm}$. If the tube is inclined at an angle of $60°$with the vertical, then upto what length the water will rise in the tube

Water rises in a vertical capillary tube up to a height of $2.0 \mathrm{cm}$. If the tube is inclined at an angle of $60°$ with the vertical, then up to what length the water will rise in the tube?

If the surface tension of water is $0.06\mathrm{ }\mathrm{N} {\mathrm{m}}^{-1}$, then the capillary rise in a tube of a diameter $1 \mathrm{m}\mathrm{m}$ is (Take, angle of contact $\theta =0°$, density of water, $\rho ={10}^3 \mathrm{kg} {\mathrm{m}}^{-3}$, $g=9.8 \mathrm{m} {\mathrm{s}}^{-2}$)

A capillary tube is immersed vertically in water and the height of the water column is $x$. When this arrangement is taken into a mine of depth $d$, the height of the water column is $y$. If $R$ is the radius of the earth, the ratio $\frac{x}{y}$ is:

The rise of liquid column in a capillary tube, if it is taken from Earth to the surface of the moon, will be: (acceleration due to gravity on the earth is $6$ times that on the moon)

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