In this simulation, you can explore the force between charged particles. You can drag the particles around the screen to change their positions. If you only want two or three of them, just set the charge on one or two of the particles to zero.
You can display (or not) an arrow representing the net force being applied to each particle. You can also use the checkboxes to display the individual forces being applied to the particles by the other particles.
