So I've created a program in C# with the XNA libraries which is meant to simulate motion between charged particles. I drew a pic to show the problem I'm having and how I'm moving the particle.
You need to show your values and the actual working you used. For instance, the horizontal separation is (1) and (2) are both Δx ... a parameter you give the system. So the only way you get a 2 in there is if you put it there.
