Answer:
The electric potential is
Explanation:
From the question we are told that
The length of the rod is
The total charge of the rod is
The length from the center is
The diagram illustrating the setup for this question is shown on the first uploaded image
From the diagram the potential at point A is mathematically represented as
Where K is the coulomb constant with a value
where q is the charge in charge the rod relative to its distance from A is mathematically represented as
This a small unit length of the rod
So
=>
Substituting values
