Derive \geotriangle P=2\gamma /r, using the "surface tension" point of view. Suggestion: Consider
the sphere to be in two halves, with the surface tension along the join balancing the
force due to \geotriangle P, which would tend to separate the two halves.
Derive \geotriangle P=2\gamma /r, using the "surface tension" point of view.
