SUMMARY
The total electrostatic potential energy of a nonconducting sphere with radius r0 and total charge Q, uniformly distributed throughout its volume, can be calculated using the formula U = k * (Q^2 / (5 * r0)). The potential V at the surface of the sphere is given by V = kQ/r0. The charge density σ is defined as σ = Q/v, where v is the volume of the sphere. The integration of the potential energy from the inner radius to the outer radius of the sphere is essential for deriving the final expression.
