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

Find the general formula for the x component of the electric

field if the charge density p varies only with x throughout all

space.

2. Relevant equations

3. The attempt at a solution

I started using the poisson equation [tex]\bigtriangledown \bullet \bar{E} = \frac{p}{\varepsilon_{0}}[/tex]

From the problem text, I know that p has only the x component and so also E has only the x component.

With these information, i tried to calculate the poisson equation, obtaining :

[tex]\frac{\partial E_{x}}{\partial x} =\frac{p(x)}{\varepsilon_{0}}[/tex]

But, i dont know how to continue the calculations... Can you help me ?
