Thanks for the response DaTario.
I've started with that method - finding the field at a point P = (x,y,z) (point \vex{r} in spherical) by integrating the charge from the positive distribution \rho_{+}=\rho_{0}exp(-(r^{2})/(2\sigma^{2})) and then the negative distribution...
Hi,
I understand how to get the electric field between two spheres of uniform charge,
\vec{E} = \frac{\rho \vec{d}}{3 \epsilon_0}
which is simplified because at a point \vec{r}, the vectors from each charge center combine to give the distance, \vec{d}, between centers (since \rho's can...
