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 −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 −q but a negative charge of different magnitude, say −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 −q but a negative charge of different magnitude, say −Q. Find the electric field at any point between the spheres (rarb. Express your answer in terms of the given quantities and appropriate constants. E = ?
