Problem 10. Consider three \"thin\" concentric conducting spherical shells with radii a

Problem 10. -Q a b c Consider three "thin" concentric conducting spherical shells with radii a < b < c respec- tively. Initially all three shells are neutral. Then a negative charge Q) is placed on the innermost sphere, a matching positive charge +Qo is placed on the outermost sphere, and the arrangement allowed to come to equilibrium. a) Find the electric field everywhere and plot it. You will probably find this easier to do if you let each shell have a small (relative to a) finite thickness as drawn above. b) Make a table showing the net charge on the inner and outer surfaces of each con- ducting shell.
