Answer:
V = 0
Explanation:
To find the potential at the middle of the two charges with opposite signs, you use the following formula:
[tex]V_T=V_1+V_2=k\frac{q}{r}-k\frac{q}{r}=0V[/tex] (1)
where you have used the fact that the charges are the same and the distances are the same.
The electric potential is zero at the point in the middle of the two charges
