Haha - so, I've graduated since I originally posted this problem a couple years ago, but I actually just pulled out a box of old schoolwork to sort through. If I can find the solution, I'll post it.

There actually i s surface charge - picture a surface of thin dielectric in the xy-plane. If you polarize the whole thing with an e-field in the z-direction, the dipoles at the top of the plane will have their positive charges pointing up (giving a positive surface charge). Likewise, the bottom...

Homework Statement Determine the electric field intensity at the center of a small spherical cavity cut out of a large block of dielectric in which a polarization P exists. The Attempt at a Solution charge densitysurface = P(dot)n --> charge densitysurface = P(dot)r This is about as far as...
