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 +q on the inner sphere and charge −q on the outer spherical shell. Take V to be zero when r is infinite.
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 ( ra < r < rb).
Part I
Suppose the charge on the outer sphere is not-q but a negative charge of different magnitude, say -Q. Find the electric field at a point outside the larger sphere at a distance r from the center, where r > rb.
Gauss law of electrostatic is used which states that electric flux through a closed surface be equal to the ( 1/ epsilon not ) times to the total enclosed charge by closed surface.
If any doubt remains then mention in comment i will reply
asap
