Diagram alongside shows an uncharged insulated conductor AB, which is in electrical contact with gold leaf electroscope plate C. A negatively charged rod is brought near the end A. Answer the following questions:
(i) What charge appears at A and why?
(ii) What charges are present at B, C and D and why?
(iii) If the negatively charged rod is taken away, state your observation.

(i) Positive charges appear at A. The presence of negatively charged rod, repels the electrons from end A towards end B. As end A develops deficiency of electrons, therefore, it gets positively charged.
(ii) (a) No charges are present at B as the electrons drift to C.
(b) Negative charges are present at C, D and P because the electrons from A drift to these points.
(iii) The gold leaves of G.L.E collapse.
