  1. So all we need to do is to find that along just one of those longitude. Right?
  2. So if i find that cohesive force along the periphery, does that give me the same force that is required to hold the molecules on the curved surface together?
  3. In the case of equilibrium of hemispherical drop, what i know is that the surface tension is responsible for holding the hemispherical drop with the other hemisphere thus forming a spherical drop and the surface tension also holds the liquid on the curved surface thus giving it the curved shape. Why is force due to surface tension measured only along periphery(T2πr) whereas the surface tension exists also on the surface(2πr²) ?
