Solving a problem in physics section 59 paragraph 63 el

63. The conductive capacity of the sphere C = 5,0 pF charged to a potential φ = 2,0 kV. Determine the energy W of the electric field, enclosed in a spherical layer between the sphere and concentric with its spherical surface, the radius of which is 4 times greater than the radius of the charged sphere.
