Two concentric spherical shells of diameter 14.0 cm and 26.0 cm are used to form a spherical capacitor. The charges on the inner and outer shells are -4.00 μC and +4.00 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 kQ given by E= where k is Coulomb's constant and Q is the charge on the shell. kv (b) If the space between the two shells is filled with air, determine the capacitance. pF
