We have three identical metallic spheres $A, B$ and $C$. $A$ is given a charge $Q$, and $B$ and $C$ are uncharged. The following processes of touching of two spheres are carried out in succession. Each process is carried out with sufficient time.
$(i)$ $A$ and $B$ $(ii)$ $B$ and $C$
$(iii)$ $C$ and $A$ $(iv)$ $A$ and $B$
$(v)$ $B$ and $C$
The final charges on the spheres are
$(i)$ $A$ and $B$ $(ii)$ $B$ and $C$
$(iii)$ $C$ and $A$ $(iv)$ $A$ and $B$
$(v)$ $B$ and $C$
The final charges on the spheres are
