In a capillary tube of radius ‘R’

Sahay Sir > Question Answers > In a capillary tube of radius 'R'
In a capillary tube of radius ‘R’, a straight thin metal wire of radius ‘r’ (R > r) is inserted symmetrically and one end of the combination is dipped vertically in water such that the lower end of the combination is at same level. The rise of water in the capillary tube is [T = surface tension of water, ρ = density of water, g = gravitational acceleration]
