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

"Compute the electric field due to an infinite line charge by integrating the expression obtained from the inverse square law."

2. Relevant equations

I think that the equation required is:

[itex]E(\bold{r}) = \frac{1}{4 \pi \epsilon_0} \int_{-\infty}^{+\infty} \frac{(\bold{r} - \bold{r}') \sigma}{|\bold{r} - \bold{r}'|^3} dx[/itex]

3. The attempt at a solution

Well, I don't know what to put in the above integral forrandr', or even if the above integral is even right...

Thanks for any help :) .
