Hello all, I am new to PF; this is my first post. I am currently taking a physics class on electricity and magnetism. I am trying to find an equation to calculate the final position of a charged particle p, given that there are n other particles. Known: + initial (positions and velocities) and charges of all particles (including particle p) + mass of particle p + final time t Find: + exact final position of particle p after the given time t I tried working it out on paper, but I got stuck and don't know how to simplify it. Does anyone know the equation for this?
