A continuous line of charge lies along the $x$ axis, extending from $x=+x_{0}$ to positive infinity. The line carries charge with a uniform linear charge density $\lambda_{0}$ . What are the magnitude and direction of the electric field at the origin?

Step 1
First, we need to consider a small element of charge located at a distance $x$ from the origin. The length of this element is $dx$, so the charge of this element is $dq = \lambda_0 dx$. Show more…
