Im still on high school so I dont know where this question belongs to, I dont know even what is the exact subject of this question, so I would like you more experienced members to help me understand what exactly Im asking and where I can find information about it:(adsbygoogle = window.adsbygoogle || []).push({});

"In an empty universe, two particles, A and B, are instantly created at time=0s with an arbitrary position, mass, charge and velocity. They interact by electromagnetism and nothing else. How to find their positions in function of time?"

I have attempted solving it this way: their positions are the an integral of their velocities, right? Their velocities are an integral of their accelerations. Their accelerations are a function of their distances, that is a function of their positions. So in the end I had something like:

[itex]posA(t) = \int_0^t \int_0^t(\frac{k*qA*qB}{|posA(t)-posB(t)|Â²*mA}) dtdt[/itex]

Well its probably wrong and even if it were right Id have no idea of how to solve it. But you got the idea. Thoughts please.
