In this simulation, the two charged particles (in green) are each randomly assigned a sign and a
magnitude that is either 1, 2, 3, 4, or 5 nC. Your goal is to determine their charges - when you have figured
out what they are, set the charge sliders to those values and check your answer.
to help you determine the charges, the field vector pattern near the charges is shown.
There is also an electric field sensor (in red) that you can click-and-drag, moving it around the screen to sense both the electric field and the electric potential. The readouts of the position, field, and potential are at the bottom.
