A rod of length L has a total charge Q uniformly distributed along its length. The rod lies along the x axis with its center at the origin.What is the electric potential as a function of position alon gthe x axis for x>L/2

2. Relevant equations

V=∫kdq/r = ∫kQ/r dx I'll add limits of integration at the end to make it easier

V=kQlnr integrated from x+L/2 to x-L/2 which gives me kQln((x-L/2)/(x+L/2)) but the answer was kQ/L * ln((x+L/2)/(x-L/2))

I don't understand where they got the L from and how my log was the opposite

3. The attempt at a solution
