Surface tension_another problem

  1. Nov 15, 2008 #1
    Suppose that there is a small spherical ball of mass 'm' floating on surface of a liquid due to surface tension. The contact angle between ball and liquid is theta. Is there any way to calculate exactly as what fraction of ball will be inside the fluid. Buoyancy should not be neglect.

    i shall rephrase my question.
    A small spherical ball is floating in liquid layer due to surface tension. Thus it depresses the liquid layer as if it is an elastic membrane. So shall we say that buoyant force doesn't act on it?
