Accurate Analytic Formulae for the Far Field Effective Potential and Surface Charge Density of a Uniformly Charged Sphere formulae for the far field effective potential and surface charge density. These formulae are valid over the entire range of ka and display good
Simple yet accurate formulae are presented for the far field accuracy for all surface potentials of experimental interest (£200 mV).
