2. A point charge +q is at the center of thick walled conductor with inner radius a and outer radius 3a. The thick-walled conductor has a net charge of +2q. You may assume spherical symmetry. The knowns are q, a, and E. 1 (a) Find the electric field at r=a. (5 points) 2 thick-walled conductor (b) Find the electric field at r=2a. (5 points) (c) Find the electric field at r=4a. (5 points) point charge (d) Find the inner and outer surface charge densities on the conductor. (5 points) 2.
