SUMMARY
The electric field equation for an electrified sphere can be derived using Gauss's theorem and the concept of gradient in spherical coordinates. For points inside the sphere (r < R), the charge distribution must be considered, particularly for metallic spheres where charge resides on the surface. The relationship between electric potential (V) and electric field (E) is expressed as V = E · d, but it is essential to apply the correct spherical coordinate transformations to derive accurate results.
