(It is, however, axially symmetric about p That is, if you rotate the
position vector r  about  p, keeping q fixed, the points corresponding
to P on the cone so generated will have the same potential as at P )
(ii) The electric dipole potential falls off, at large distance, as 1/r 2, not as
1/r, characteristic of the potential due to a single charge (You can
