A nonconducting sphere with net charge +Q uniformly distributed throughout its volume creates an electric field of magnitude E at point P(not in the center) that is within the sphere. If the sphere is a conducting sphere with charge +Q, how would the magnitude of the electric field at point P compare to that for the nonconducting sphere?

1 answer

The magnitude of the electric field at point P would be the same for both the nonconducting and conducting spheres. The electric field is determined by the charge of the sphere, not its material properties.
