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

An electric charge Q has been evenly divided over a line with the lenght L. Calculate the electric field in the field spot X0. X0 > L

2. Relevant equations

3. The attempt at a solution

E = 0SL(dQ/(4*pi*E0*X0^2))

0SL = the integral over 0 to L >_<

dQ = Q*dx/L , I think...

E = (Q/(4*pi*E0*(X0^2)*L))*0SL(dx)

E = (Q/(4*pi*E0*(X0^2)*L))*L

this is not a correct answer so i wonder where Im failing.

The right answer should be (Q/(4*pi*E0))*(1/(L(X0 - L)) - 1/(L*X0))
