ewe are considering is given by supposing the two halves of itssurface oppositely electrified to a surface-density proportional tothe thickness of these displacement-layers. To prove this, let us investigate the electric force at a point, m,within the two nearly coincident spheres. The force due to… … axis; the points where it cuts K 36 ELECTRIC INFLUENCE [25- sides am and ma are respectively parallel and proportional totlie two forces acting at M, and consequently the third side, aa,is parallel and proportional to their resultant. The resultant is therefore ^ irp . aa. -^, and is independent of…
