r=0 is impossible because every particle, including particles possessing electric charge have non-zero size.

e=((4pie epsilon)q)/r^2  is an approximation(for sufficiently large r) that breaks down as r→0, at very small r, quantum electrodynamics should be used. By the way, NO physical quantity can ever have infinite value because no matter how high its value, it would not be infinite.Infinity is not a number, it is only a limit.
