Question
thin uncharged conducting spherical shell has a charge q carefully placed at its centre through a small hole. The charge q does not touch the shell. What is the charge on the shell?
Correct Answer
Option A is the correct answer.
Detailed Explanation
By electrostatic induction, inner surface gets –q, outer surface gets +q, but net charge on shell remains 0 (shell was uncharged and isolated). The question asks 'charge on the shell' meaning net charge = 0.
Hint
Net charge on isolated uncharged shell = 0.
