Coulomb's Law: Maximum Force & Distance?

[QUOTE="Nugatory, post: 5575040, member: 382138"] Coulomb's law in the common form that you're using is for point charges, idealized objects with no size at all. Thus, no matter how close they are to one another, your charges won't touch and stick together. Of course no real charged object is an ideal point particle; it has to have a surface and some size and shape. If you bring two of these close enough to touch, you'll have to use the more complicated integral form of Coulomb's law (google for "Coulomb's law integral") to calculate the force between them, and to do that you need to know the shape of both objects and how the charge is distributed within them.
