aviatorhi, the reason is simple: I did a search and this thread and more specifically post #52 were very related to an ongoing debate we are having these days. I think I stated this in my introduction. I have tried to say it in different words and hope this has satisfied your curiosity.
If you feel like it you may now tell me if it is 1, 2 or 3. Your first answer seems to indicate that the third answer could likely be your choice.
For clarification this debate has nothing to do with charges. I can't see how the other answers relate to my question so 3 it is again.
Other opinions are welcome, thanks
