> > Opposite charges are attracted to each other and like charges are repelled. > Why? > The fact that there are attractions and repulsions lead us to postulate that there are two kinds of charge. Why they attract and repel is no more known than why two objects attract each other gravitationally. They just do and gravity is the name we give this phenomenon. Electricity is the name we give to the phenomenon related to forces by charges. We don't know what it IS, but we know pretty well what it DOES. -- ------------------------------------------------------------------------------- Van E.
