[Phys-L] Re: Elecric Field Lines

So the somewhat surprising fact is that NO field line approaches
the y-axis for very long.

Actually, that didn't seem at all surprising to me. I thought about the
field far from the charges, which ought to look a LOT like a single
point charge of 2Q at the origin. Since that field is spreading
radially, then any E field lines leaving the charges must eventually
bend around to head out mostly radially from the origin - i.e. away from
the y axis.

Shows the power of thinking about the limiting case!
