Another very simple caseis that of a sphere suspended within a spherical shell whichcompletely surrounds it (Fig. 7). Here the lines of force arealso radii between the surfaces, and if we suppose the outershell connected with the earth there will be no lines of forcearound it; that is, outside. Hence, all the force is in the inter-mediate space between the sphere and shell, and there is no forceoutside. If the interior body, instead of being a sphere, were.
