Charged Spheres Again

The solid purple spherical conductor is placed inside a spherical conducting shell and given a net charge of 2 mC.

(a) Find the electric field at

1. r = 1 m
2. r = 3 m
3. r = 5 m
4. r = 9 m

(b) Where is the charge and charge density on each surface of the two conductors?

(c) Find the electric potential at

1. r = 1 m
2. r = 3 m
3. r = 5 m
4. r = 9 m

(d.) Sketch graphs of the electric potential vs. r and E-field vs. r, both from r = 0 to infinity where r is the distance from the center of the solid sphere.
