Q. Consider an uncharged conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then,
(i) negative and uniformly distributed over the surface of sphere
(ii) positive and uniformly distributed over the surface of sphere
(iii) negative and appears at a point the surface of sphere closest to point charge.
Answer: (iv) Zero
Equal and Opposite charges appear on the nearby conductor due to induction, but still net charge on the conductor is zero. Correct option (iv)
