A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 12.5 cm and the outer sphere has radius 15.6 cm. A potential difference of 110 V is applied to the capacitor.
(a) What is the energy density at r = 12.6 cm, just outside the inner sphere? in J/m3
(b) What is the energy density at r = 15.5 cm, just inside the outer sphere? in J/m3
