Why do the electrons in a charged body (take the metal for example)
that has an edged (I mean a special shape like ...
|____/ or similar to this |___> )
goes around (mostly) the edge of that shape (which is in the left side of
the figure drawn).
Electrons in a negatively charged body go near the edges because they push
away from each other. The electrons "try to get" as far from other
electrons as is possible. Consider a cube. By grouping together at the
eight corners of a cube, electrons can be near one-eighth of the other
electrons but far away from seven-eighths of them. It works out as better
than being evenly spaced.
