Gauss' Law?

## The Attempt at a Solution

I'm not sure if I should be using Gauss' Law for this question, because I've never heard of it or learned about it. I'm currently taking multi-variable calculus (gradients, vectors, etc.). From what I know, the gravitational force should be found using an integral from R to infinity for the area of the plane... but I'm not sure what to do from there.

G*∫((mσ)/(Z^2))*dA from R to ∞?
