(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

There is an infinite conducting charged metallic wire. What will the potential at a distance r from the wire be?

3. The attempt at a solution

I know that [tex]E=\frac{\lambda}{2\pi \epsilon r}[/tex] and [tex] E=\frac{-dv}{dr}[/tex].

Integrating the expression for the electric field wrt r, [tex]V(r)=-\frac{\lambda}{2\pi \epsilon} logr[/tex]

This, however, isnt the answer. Why?
