tions regarding Spherical Conductors. 71 Let m denote the quantity of electricity in the electricalpoint Jf; / its distance from G thecentre of the sphere, and a the radiusof the sphere. If the expression for the electricaldensity at any point E of the internalsurface be A. * (A, a constant); the… … a-r the total resultant force, due to the given electrical point andto the electrified surface, will vanish at every point external tothe spherical surface, and consequently at every point withinthe substance of the conductor; so that the condition of electricalequilibrium (§ 72), in the prescribed…
