Question: A metal sphere with radius ra is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb. There is charge +qon the inner sphere and charge âˆ'q on the outer spherical shell. Take V to be zero when r is infinite.

Part G. Suppose the charge on the outer sphere is not âˆ'q but a negative charge of different magnitude, say âˆ'Q. Find the potential of the inner sphere with respect to the outer.

Express your answer in terms of the given quantities and appropriate constants. V_{ab} = ?

Part H. Suppose the charge on the outer sphere is not âˆ'q but a negative charge of different magnitude, say âˆ'Q. Find the electric field at any point between the spheres (ra<r<rb).

Express your answer in terms of the given quantities and appropriate constants. E = ?

Part I. Suppose the charge on the outer sphere is not âˆ'q but a negative charge of different magnitude, say âˆ'Q. Find the electric field at a point outside the larger sphere at a distance r from the center, where r>rb.

Express your answer in terms of the given quantities and appropriate constants. E = ?
