A capillary of the shape as shown is dipped in a liquid. Contact angle between the liquid and the capillary is `0^@` and effect of liquid inside the mexiscus is to be neglected. `T` is surface tension of the liquid, `r` is radius of the meniscus, `g` is acceleration due to gravity and `rho` is density of the liquid then height `h` in equilibrium is:
