Sorry, the problem uses q for the point charge outside, and +Q for the charge of the sphere. I'm not exactly sure if they're suppose to be the same, but if we assumed they were not equivalent, would the charge of the interior surface in (2) be -(Q+q)? Thanks

Homework Statement (1)A conducting sphere w/ charge +Q is surrounded by a spherical conducting shell. What is net charge on inner surface of the shell? (2) A charge is placed outside the shell. What is the net charge on the inner surface now? (3) What if the shell and sphere are not...
