During the capillary rise of a liquid in a capillary tube,the surface of contact that remains constant is of

Which of the following statements is false?

Water rises to a height $h$ in a capillary tube at the surface of the Earth. On the surface of the moon,the height of the water column in the same capillary tube will be:

Write the formula for the height of a liquid column in a capillary tube.

$A$ capillary tube is immersed vertically in water,and the water rises to a height $h_1$ on the Earth's surface. When this arrangement is taken into a mine of depth $d$ below the Earth's surface,the height of the water column is $h_2$. If $R$ is the radius of the Earth,the ratio $\frac{h_2}{h_1}$ is:

In the state of weightlessness,a capillary tube is dipped in water,then water
