Electric field produced by a uniformly polarized sphere

You don't need to specify the $z$ direction. To get a uniform polarization in a linear dielectric, you need to immerse it in a uniform external field, $E$, where $E$ is the value far from the field. ...

What is $E$ with respect to the relation between an electric field and its polarization density?

The $\mathbf{E}$ in the formula is the electric field at equilibrium $\mathbf{E}_\mathrm{total}$ (In the following answer I shall use $\mathbf{E}_\mathrm{total}$ in place of $\mathbf{E}_\mathrm{n}$). ...
