1. The problem statement, all variables and given/known data 2. Relevant equations ##σ_b = \vec P ⋅\hat n 3. The attempt at a solution The polarized system could be transformed into two charged discs S1 and S2 of radius a kept at a distance L. The discs S1 and S2 have surface charge densities -P and P respectively. A) For L>>a, In this case, the system could be approximated as two equal and opposite charges kept at a distance L. So, the Electric field can be sketched as B) For L << a, The system could be approximated as a capacitor. So, the electric field inside the two discs will be uniform. And the electric field outside the two discs will be in the direction from the positive plate to the negative plate. I can't say anything more in this case. C) For L ≈ a, The electric field is perpendicular to the plates in the direction from positive to negative plate in the vicinity of the center of the plates. But, in the region far from the center, I can't say anything. Here, I need help.
