Hint for Ch. 23, special problem
Consider charge elements that are conjugate about the perpendicular bisector of P.
The contribution to E from the negative and positive infinitesimal elements will
combine to point down, horizontal components cancelling. The result for the point
dipole (Ch. 23: 25P) can be used for the conjugate pair and the linear charge
density integrated from 0 to a.
