Electric potential distribution of a charged circular rod

    1. The problem statement, all variables and given/known data
    Im trying to calculate the electric potential created by a circular rod of charge Q and radius R at a random point (not only on the rod's axis). The rod can be considered very thin.

    2. Relevant equations

    3. The attempt at a solution
    V = k \int dq/r
    My problem is how to express r in a better way. I know i have to use cylindrical coordnates (r,z) but how can i express the distance from the charge element dq when the point P is not on the rods axis?
