1. The problem statement, all variables and given/known data Show that the polarization of a material is P=Nqx where x is the displacement between the center of the electron cloud and the atomic nucleus. 2. Relevant equations P=Nqx is given and I went ahead and subbed (q/m) * E[1/(w0^2 - w^2)] for x. 3. The attempt at a solution After that I'm kind of stuck. I tried some basic manipulation with P=E([tex]\epsilon[/tex]0-[tex]\epsilon[/tex]), but I'm just shooting in the dark here. I feel like I'm missing some basic information that makes this a simple question.
