Homework Statement
A line of charge starts at [tex]x=+x_0[/tex] and extends to positive infinity. If the linear charge density is [tex]\lambda=\frac{\lambda_0x_0}{x}[/tex], determine the electric field at the origin.
The Attempt at a Solution
I'm really not sire which equations I would have to use to solve this...I am really just stuck at looking for a starting point to approach this.
I was thinking maybe [tex]E=k_e\int\frac{dq}{r^2}[/tex] might be of some use. I'm not sure how to associate electric fields with charge density, and I'm not quite sure how the infinity plays into this either. Any help would be greatly appreciated, thanks so much.
