The general formula for the electromagnetic four-vector produced by a moving charge is the Lienard Wiechert formula, which involves the retarded position of the charge. However, in the special case where the motion of the charge is a uniform velocity motion, the result becomes extremely simple, with the retarded position no longer appearing. For example, the electric potential for a uniform velocity charge located at the origin becomes simply Q/R where R is NOT the retarded position, but actually the current position.
I need to convince someone of this, and it is unlikely he can be convinced by me calculating it for him. Can anyone supply me with a specific reference from a "respected" source where the result is clear. The actual physics calculation need not be clear--I am not really trying to reason with the person as much as to show him that some respected source agrees with me.
Thanks.
