Within a spherical charge distribution of charge density `rho(r)`, N equipotential surface of potential `V_(0), V_(0)+DeltaV, V_(0)+2DeltaV, � V_(0)+NDeltaV (DeltaV gt 0)`, are drawn and have increasing radii `r_(0), r_(1), r_(2), �. R_(N)`, respectively. If the difference in the radii of the surface is constant for all values of `V_(0)` and `DeltaV` then :-
