The thin, uniformly charged rod shown in the figure below has a linear charge density λ. Find an expression for the electric potential at P. (Use k_e for ke, lambda for λ, a, b, and L as necessary.)(adsbygoogle = window.adsbygoogle || []).push({});

2. Relevant equations

dV=k*dq/r

lambda*dx=dq

3. The attempt at a solution

I integrated using the above equations and went from 0 to L. I thought this was the right way to do it but I keep getting the wrong answer.
