1)What is the charge on the inner cavity surface?

I know it is -4.00nC but why??

2)What is the electric field magnitude 3.00m from the center of the sphere?

E(4pi*r^2)=Q/E0

THE ANSWER is 3.996 V/m again I don't understand..

How much flux passes through this closed surface?

What is the net charge enclosed by the surface of this sphere?

perfect symmetry -> use Gauss' Law :)

(Gaussian surface inside the conduction outer shell)
