2. Relevant equations

EA = Qenclosed / epsilon

3. The attempt at a solution

I found the electric field outside to be [tex]\rho*d/2\epsilon_{0}[/tex]. Not sure if that helps, I don't know what to do since it says "as a function of x"

You know it's going to be linear from x = 0 to x = d/2, and at d/2 you know what it is and at 0 it's 0. So ...
 
Hmm i am not sure I follow. I understand its linear from x = 0 to x = d/2 and at d/2 its the same as Eout?

That's what it looks like to me.

So what equation expresses that?
