The energy stored in the electric field produced by a metal sphere is J. If the sphere contains C charge, its radius will be:

Answer: (2)

Solution

A charged conducting sphere has no field inside it, so all the field energy lies outside and equals the self-energy

U = = = ·,

using for an isolated sphere. Substituting the numbers,
