This is a simple question, I guess.

Imagine a perfect conductor inside a region of constant electric field, like in pic related. I can understand why the electric field should be zero inside the conductor because of the counteracting field created by the induced charges. But how about the field outside? Is it simply [math] \mathbf{E_0} [/math]? What if the material isn't a perfect conductor, but a dielectric. How I'd go about calculating the field outside?
