Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by `75xx10^-4` newton force due to the weight of the liquid. If the surface tension of water is `6xx`10^-2` newton/metre the inner circumference of the capillary must be:

A

`12.5xx10^(-2)m`

B

`6.5xx10^(-2)m`

C

`0.5xx10^(-2)m`

D

`1.25xx10^(-2)m`
