Two concentric spherical shells of diameter 13.6 cm and 29.0 cm are used to form a spherical capacitor. The charges on the inner and outer shells are −9.00 µC and +9.00 µC, respectively.
(a) Determine the potential difference from the inner to the outer shell. Use the fact that the magnitude of the electric field at a distance r from the center of the inner shell is given by E = KQ/r2, where K is Coulomb's constant and Q is the charge on the shell.
(b) If the space between the two shells is filled with air, determine the capacitance.
