An electric dipole is fixed at the origin of a coordinate system, and an electric field detector can be moved anywhere along the surface of an imaginary sphere of radius r that is centered on the origin. the radius of this sphere greatly exceeds the dipole separation, r > > d. as the detector is moved over the spherical surface, what is the ratio of the largest and smallest magnitudes of the electric field it detects, emaximum/eminimum?
