Question

A 5.71-pF spherical capacitor carries a charge of 1.70 µC.

(a) What is the potential difference across the capacitor?

(b) If the radial separation between the two spherical shells is 6.66 ✕ 10⁻³ m, what are the inner and outer radii of the spherical conductors? Hint: The capacitance of a spherical capacitor is

C = 4πε₀[r_inr_out/(r_out − r_in)].

r_in = ________ m

r_out = ________ m

When solving b, please explain to me how you were able to get the r_in and r_out when you completed the problem and started "solving" for it.
