Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-III, B-IV, C-II, D-I
Charge flows between the conductors until both are at the same potential. Charge is conserved, but some energy is lost as heat.
(A) When electric charges are shared between two conducting bodies by touching them, the potential on them — this matches (III) becomes equal. Charge stops flowing when no potential difference is left.
(B) When electric charges are shared between two conducting bodies by touching them, the charges acquired by them — this matches (IV) are in the ratio of their capacities. At the common potential V, each carries \( Q = CV \), so \( Q_1 : Q_2 = C_1 : C_2 \).
(C) When electric charges are shared between two conducting bodies by touching them, no charge — this matches (II) is lost. The total charge is unchanged (conservation of charge).
(D) When electric charges are shared between two conducting bodies by connecting a wire between them, some amount of energy — this matches (I) may be lost. The lost energy is dissipated as heat in the wire.
