Question: 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 $6\times {{10}^{-2}}\,N{{m}^{-1}}$, the inner circumference of the capillary must be


1) $1.25\times {{10}^{-2}}m$
2) $0.50\times {{10}^{-2}}m$
3) $6.5\times {{10}^{-2}}m$
4) $12.5\times {{10}^{-2}}m$
Solution: Explanation: No Explanation
Capillarity Surface Tension
