(N/A) The terms positive and negative for charges were introduced by the American scientist $Benjamin$ $Franklin$.
This naming convention is analogous to mathematical numbers,where adding a positive number to a negative number of the same magnitude results in a sum of zero. Similarly,when equal amounts of positive and negative charges are combined,they neutralize each other.
Based on this convention,an electron is defined as having a negative charge.

Why can we say that the charge of any body is always an integral multiple of $e$?

Two identical spherical conductors $B$ and $C$ have equal radii and carry equal charges. They repel each other with a force $F$ when placed at a certain distance apart. $A$ third identical spherical conductor $A$,which is uncharged,is brought in contact with $B$ and then removed. It is then brought in contact with $C$ and removed. What is the new force of repulsion between $B$ and $C$?

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 $C$
