First, sorry if something is not totally clear, I'm translating physics term the best I can!
1. Homework Statement
A sphere or radius a of permittivity ε2 is placed in a dielectric ε1. Without the sphere, we would have E = E0. We want to find the solution to this problem when ε2 = 1 (vacuum).
Seems like I'll need those test functions:
V1=-E0 + p/r3 (when r > a)
V2=-E2 (when r < a)
I figured I'll need density of charge of polarization at the surface and the field produced by these charges.
So now the thing is my last electrodynamic course was a loonng time ago and I'd kinda need a head start on this one. I'm looking through the Griffith but I can't seem to find anything to help me get this problem started.
If you guys have any ideas of links that might help that'd be great! Thanks!
