The rise of a liquid in a capillary tube depends on

The rise of a liquid in a capillary is given by,



Where S is the surface tension of the liquid, is the density of the liquid, is the radius of the capillary and is the contact angle.


Hence, the rise depends on the material as the contact angle depends on it. Option (A) is true


The rise can be equal to the length of the capillary. So it has to be greater than the capillary rise. Hence option (B) is true.


It depends on the inner radius only. So option(D) is true while (C) is false.
