The charges q sub 1 and q sub 2 are at a distance of R sub 1 and R sub 2 from the origin in the x y z plane. The distance from the origin to a point P is labeled R. Distance from q sub 1 to point P is R minus R sub 1. Distance from q sub 2 to point P is R minus R sub 2. An electric field E sub 1 is produced by the charge Q sub 1, and the electric field E sub 2 is produced by the charge Q sub 2. The resultant of both electric fields is E.
