A solid conducting sphere of radius \(R\) with net positive charge \(+Q\).
A solid conducting sphere of radius \(R\) with net positive charge \(+Q\).
A solid conducting sphere of radius \(R\) carries a net positive charge \(+Q\) and is in electrostatic equilibrium. Let \(E(0)\) and \(V(0)\) be the electric field magnitude and electric potential at the center of the sphere, respectively, and let \(E(R)\) and \(V(R)\) be the electric field magnitude and electric potential at the surface of the sphere. Taking \(V = 0\) at infinity, which of the following correctly compares the electric field magnitudes and electric potentials at these two locations?
