We know the magnitude of the electric field of a dipole at a location on thexaxisand at a location on theyaxis,if we are far from the dipole.

(a)Find?V=VB?VAalong a line perpendicular to the axis of the dipole shown in the figure below. Do it two ways: from the superposition ofVdue to the two charges and from the integral of the electric field. (Use the following as necessary:q,?0,s,d.)
