HW4.5 Given: Find: cm a 3 ? A C cm b 8 ? D C 2 . 2 d ? A Q v 8 . 2 V ? D Q The two spherical-shell capacitors shown in the diagram have inner radii of a = 3 cm and outer radii of b = 8 cm. The space between the spherical plates of capacitor C A is filled with air and in capacitor C D the space is filled with a dielectric with = 2.2. Calculate the two capacitances. The two capacitors are connected to an E = 2.8 V battery using the circuit shown in the diagram. Calculate the charge (including the appropriate algebraic sign) that appears on the inner plate of C A when fully charged. Calculate the charge that appears on the outer plate of
