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]

When one end of the capillary is dipped in water, the height of water column is h. The upward force of 105 dyne due to surface tension is balanced by the force due to the weight of water column. The inner circumference of the capillary is (Surface tension of water =7×10^−2N/m)
