Question
A metal sphere with radius ra is supported on a insulating stand at the center of a hollow, metal, spherical shell with radius rb. There is a charge +q on the inner sphere and charge -q on the outer spherical shell.
A) calculate the potential V(r) for (i) r<ra (ii) ra < r < rb (iii) r > rb. Take V to be zero when r is infinite.
C) Show that the electric field at any point between the spheres had magnitude E(r) =(Vab /(1/ra -1/rb ))(1/r2 )
D) Find the electric field at any radical distance r > rb or outside of the outer spherical shell.
