Step-by-step explanation:
The electrical force between two unlike charge is given by :

k is electrostatic constant
q₁ and q₂ are two charges
r is the distance between charges
It is clear that the electric force is inversely proportional to the square of the distance between them.
The graph F as a function of r for two positive charges is shown in the attached figure. It is a hyperbola.
A graph can't be a function if there is a vertical line.

I’m really sorry I’m not sure
