## Homework Statement

You are given a charge distribution that is a uniform line charge (λ) extending from –L to L along the x-axis. Calculate the potential along the z axis. Use the given value for the electric field to calculate the line integral and verify part a.

The given value for the electric field is...

k(2*Lamda*L)/(Zsqrt(z^2+L^2)

## The Attempt at a Solution

My initial thought process was to use the equation V=k*integral[(lamda/r)dl] where r is equal to sqrt(z^2+l^2). I attempted to solve this integral using tables and got...

V=k*lamda*[ln{2sqrt(z^2+l^2)} +2l] evaluated from l=L to l=-L.

I need help proceeding from here, especially with the second part of the problem.
