Okay I'm really confused with continuous charge distributions, so I'm totally stuck...(adsbygoogle = window.adsbygoogle || []).push({});

A continuous line of charge lies along the x axis, extending from x=+x_0 to positive infinity. The line carries a uniform linear charge density lambda_0. What are the magnitude and direction of the electric field at the origin?

I have no idea where to approach or how to setup this problem up really.. What I tried to do is this..

Since, lambda = Q / L = dq / dx

E = int dE

= int k_e dq / r^2

= k_e int lambda dx / x^2

And then I'm completely stuck.... Do I need to find lambda or just integrate? or...?

Any help is greatly appreciated.

Thanks.
