Unformatted text preview: (c) (10 points) Find the electric potential at point P relative to infinity. 3. A solid conducting sphere of radius a carries a positive charge Q . It is enclosed by a thick conducting shell with inner radius b ( b > a ) and outer radius c that carries no net charge. A second thick conducting shell with inner radius d ( d > c ) and outer radius f encloses the first conducting shell and carries a net charge -Q. (a) (10 points) Find the charge on each of the five surfaces. (b) (10 points) Find the difference between the potential of the solid conducting sphere and the potential of the first (smaller) conducting shell. (c) (10 points) Find the difference between the potential of the first conducting shell and potential of the second (larger) conducting shell. (d) (10 points) Find the electric field outside the second conducting shell. (Useful constant: k = 1/4 πε = 8.99×10 9 Nm 2 /C 2 )....
