The path of charged particles in electrostatic field is completely indepedent of mass and charge; the path depends on the kinetic energy. From another point of view the time taken to travel along a path does depend on mass and charge. It is a classic result in the motion of charged particles in electric and magnetic fields that in magnetic fields the ...


Thanks laying out your work so neatly in the question. I think the solution is the following $$\Delta KE= \int_{r_a}^{r_b}{ KQq \over r^2} dr$$ where $r_a$ is the initial position and $r_b$ is the final position (and I have added $q$ as the charge of the point charge). so, for example, if the point charge goes from $r$ to $2r$ we have two positive ...
