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

• A
  $\frac{11Q}{32}, \frac{5Q}{16}, \frac{11Q}{32}$
• B
  $\frac{11Q}{32}, \frac{11Q}{32}, \frac{5Q}{16}$
• C
  $\frac{8Q}{8}, \frac{5Q}{16}, \frac{5Q}{16}$
• D
  $\frac{5Q}{16}, \frac{11Q}{32}, \frac{11Q}{32}$
