Quiz-IV

1. Is it correct that the potential due to the charges \(q\) and the image charge \(q'\) on the inner surface constant value everywhere? If yes, what is this value?
2. Is the given answer for potential outside the shell for \( r > r_2\) correct? If not, what value should the potential have on the outer surface?
3. Is the image solution given here for electric field inside the shell, \(r< r_1\) is correct or not? Give reasons. What is the potential inside the shell?
4. If the given solution has mistakes, give your solution for the potential for (a) \(r< r_1\)  (b) \(r > r_2\) . If you wish you may consider some special case and solve the problem in suitable approximation.
