Imagine a short dipole at the center of a spherical surface. If the magnitude of the electric field at a certain point on the surface of the sphere is 10 NC-1, then which of the following cannot be the magnitude of the electric field anywhere on the surface of the sphere?

(i) Let electric field at '1' be 10 NC-1, then at '2' it is 5 NC-1 and at any other point on surface of sphere electric field will be from 5 NC-1 to 10 NC-1.(ii) Let electric field at '2' is 10 NC-1, then at '1 it is 20 NC-1 and at any other point on surface of sphere electric field will be from 10 NC-1 to 20 NC-1.
