Gauss' Law for a Spherical Conducting Shell

Gauss' Law applied to an insulating charged sphere surrounded by a charged conducting spherical shell.

Thanks so much! I could not for the life of me figure this out.

Also should the total charge of the set up be Q not -Q as the charges of the conducting sphere cancel?

[MrPumpkinPi]

If the conducting shell moves charges to counteract the electric field from the sphere wouldn't area II be 0?

Why E 1 is not 0?. According to your lecture, E 1 should be 0 because it is inside of a conductor like E 3..
