We're on the same page then. Excellent! Thanks! Your random musings brought out my insight :D

I think that's a fair way to look at it, except I don't understand what you mean by "For the outer shell, then, there's nothing inside so... nothing happens." Basically, the way I see it, the outer shell is surrounding a positive charge (positive potential, l like you said), so all the...

Fyzxfreak, I think the post before your edit hit it on the head--grounding would get rid of the positive charges and leave a net negative charge on the spheres.

The shells were initially grounded, but then released. But why would that make a difference? Wouldn't grounding make the shells neutral?

That's something along what I was thinking, but wouldn't that happen for all cases with a (initially grounded) conductor near a charge? This "neutralizing" of the electric field beyond the conductor?

Hey, Completing AP Problems, I ran into a puzzling answer. Basically, there was a conducting sphere with charge Q on it and radius R1, and then around it two hollow hemispheres were placed (forming a spherical capacitor) which had no charge, with Radius R2 at the inner edge and R3 at the...
