For this problem I am giving the following:

An infinite slab of charge parallel to the yz plane whose density is given by:

p(x)= t, -b<x<b;

0, |x|>b;

Where t and b are constants.

And I am to find the electric field.

I am pretty confused on how to do this problem. I know that the electric field is in the x direction, and that is also where the normal to the surface is directed. So I thought it would be:

[tex]2 v E =\frac{q}{\epsilon}[/tex] where the q = [tex]\frac{p}{v}[/tex]

Where v is the volume, similar to how you do an infinite sheet but I don't get the right answer. But then q would be 0 for outside of b and that is not right so I guess my method is completely wrong.
