I am a bit stuck with how to approach this questions;
"A thin conducting spherical shell of radius a carries a charge q. Concentric with this is another spherical shell of radius b>a carrying a net charge Q. Describe how the charge is distributed between the inner and outer surfaces of the shells. What is the capacitance of the two shells?"
Is the answer...just that all the charge lie on the surface of the two spheres? The electric field inside a conducting sphere is zero..so how does that work..there would be charge lying on the surface of the inner sphere which itself is inside the larger sphere so there would then be an electric field inside the larger sphere. Sorry I'm really a bit confused and would really appreciate some help with this question.
