ICSE Class 9 Answered
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.
