@Starior Yes. I used $+\delta$.

@Starior I used the cylindric coordinates, where $z$ is a line of symmetric of this rings.

@Starior Use Gauss law for this.

comment Integral of inverse of square root of a quadratic
@Starior Provide a physical context of problem. That would be more useful than the pointless $a$, $b$, $c$, $g$ and $q$.

What's that? Replace $c$ by $g$, than you need to only integrate a constant. The question is malformed, btw.

Why didn't I notice this by myself? That's an awesome and easy way to do this!

@TroyWoo Thanks, forget about $a$, actually it's less than zero, so $-a+\varepsilon$ is positive and a bit greater than $a$.

And please, leave only question here, without any other solved examples...
