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.
