Column-I gives certain situations involving two thin conducting shells connected by a conducting wire via a key K. In all situations one sphere has net charge +q and other sphere has no net charge. After the key K is pressed, Column-II gives some resulting effect. Match the figures in Column-I with the statements in Column-II.
Column I | Column-II | ||
(A) | (I) | Charge flows through connecting wire | |
(B) | (II) | Potential energy of system of spheres decreases. | |
(C) | (III) | No heat is produced. | |
(D) | (IV) | The sphere I has no charge after equilibrium is reached. |

Initially, the potential difference exist between both shells, so positive charge is flow from high to low potential.
Very system wants to acquire minimum potential energy if possible for stability. So charge flown to achieve it:
As explained in [a], charge flow does not depends on the size of sphere.
Charge flow through wire until the potential becomes same for both shells.
Potential is same everywhere inside a conducting shell. So no charge is flow through connecting wire, so no heat is produced.
