Potetial Difference between center and point r

1. Homework Statement
A cylindrical conductor of length L and radius R, L » R, carries a charge Q. 1. Neglecting boundary effects; evaluate the potential difference between a point at distance r from the center of the cylinder, and the center. Assume r to be of the same order of magnitude as R but external to the cylinder.

2. Homework Equations


3. The Attempt at a Solution
I would set the potential at the origin equals to 0, then I would calculate the potential at a distance r by finding the electric field and taking the negative integral of it.
