Answer» Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by $75 \times 10^{- 4} N$ force due to the weight of the liquid. If the surface tension of water is $6 \times 10^{- 2} {Nm}^{- 1}$ , the inner circumference of the capillary must be (Assume angle of contact= $0$ )
