Water rises up to a height $h$ in a capillary tube of a certain diameter. This capillary tube is replaced by a similar tube of half the diameter. Now,the water will rise to a height of:

Why does the mercury level fall in a capillary tube? Explain.

Two capillary tubes of different diameters are dipped in water. The rise of water is

Two capillary tubes made of the same material are dipped in the same liquid. If the heights of the liquid in the tubes are $2.2 \ cm$ and $6.6 \ cm$ respectively,what is the ratio of their radii?

The height of a liquid column raised in a capillary tube of a certain radius when dipped in liquid $A$ vertically is $5 \ cm$. If the tube is dipped in a similar manner in another liquid $B$ with surface tension and density double the values of liquid $A$,the height of the liquid column raised in liquid $B$ would be $........ \ m$.

$A$ capillary tube of radius $R$ is immersed in water and water rises in it to a height $H$. The mass of water in the capillary tube is $M$. If the radius of the tube is halved,the mass of water that will rise in the capillary tube will now be
