A spherical capacitor is formed from two concentric spherical conducting shells separated by a vacuum. The inner sphere has a radius of rarar_a = 12.0 cm, and the outer sphere has a radius of rbrbr_b = 14.8 cm. A potential difference of 120 VV is applied to the capacitor.

a. What is the capacitance of the capacitor? Use ϵ0ϵ0epsilon_0 = 8.85×10−12 F/mF/m for the permittivity of free space.

b. What is the magnitude E1 of the electric field E at radius r = 12.8 cm, just outside the inner sphere?

c. What is the magnitude of E at r= 14.7 cm, just inside the outer sphere?
