A small charged ball lies within the hollow of a metallic sphericalshell of radius R. Here, for three situations, are the net chargeson the ball and shell, respectively:
1 +4q, 0
2 -6q, +10q
3 +16q, -12q
(a) Rank the situations according to the charge on the innersurface of the shell, most positive first (use only the symbols> or =, for example 2=3>1).
(b) Rank the situations according to the charge on the outersurface, most positive first (use only the symbols > or =, forexample 2=3>1).
