2, a E, 7. A capacitor consists of two concentric spherical shells of radii, R. and R. The space between them is filled with a dielectric of relative permittivity, &, from R, to a (R<a<R.) and another of relative permittivity, 26, from a to R, as shown in a figure. 22 Find a capacitance (C) of the capacitor.
