ty at any point E of the conduct-ing surface. Draw MA perpendicular to theplane, and let its leng-th be denotedby p. We may, in the first place,conceive that instead of the plane sur-face we have a spherical conductingsurface entirely enclosing the air inwhich M is insulated; and, suppos-ing the… … 74 On the Mathematical Theory of Mectricity. [v. In this, let a be supposed to be iufinitely great; the secondterm within the vinculum will vanish, and we shall have simply p= ^^P- (A) for the required electrical density at the point E of the in-finite plane electrified inductively through the…
