Homework Statement
Imagine that a particle with positive charge +q is placed on the x-axis at x=+a and a particle with negative charge -2q is placed on the x-axis at x= -a. Find the potential at all points along the y axis.

The Attempt at a Solution
This isn't a homework problem, it's just a problem in the book I'm working on to get a better understanding of electric potential. I was wondering if someone could explain electric potential to me, and i figured the easiest way would be with a problem. The answer is given in terms of k, q, a, and y.
I know that had the it been -q instead of -2q the answer would be zero, but I am not sure how the physics works when it is -2.
