(N/A) The lighting of a lamp is due to the phenomenon of $Capillarity$.
In a lamp,the wick consists of fine pores or capillaries.
When the lamp is filled with oil,the oil rises up through these fine pores of the wick due to the surface tension of the liquid.
This process is known as capillary action,which allows the oil to reach the flame at the top of the wick,enabling the lamp to burn continuously.

When two capillary tubes of different diameters are dipped vertically,the rise of the liquid is

Two capillary tubes of same diameter are put vertically one each in two liquids whose relative densities are $0.8$ and $0.6$ and surface tensions are $60$ and $50 \text{ dyne/cm}$ respectively. The ratio of the heights of the liquids in the two tubes $\frac{h_1}{h_2}$ is:

Water rises to a height of $16.3 \, cm$ in a capillary tube of height $18 \, cm$ above the water level. If the tube is cut at a height of $12 \, cm$ above the water level,then:

Water rises in a capillary tube to a height such that the upward force of surface tension balances the downward force of $75 \times 10^{-4} \ N$ due to the weight of the water. If the surface tension of water is $12 \times 10^{-2} \ N/m$,the internal circumference of the capillary must be:
