Problem 23.2: What is the net charge?
Please wait for the animation to completely load.
The electric field lines, due to four charged particles, are shown in the applet (position is given in meters). You can click-drag any of these particles. If you overlap two charges, their charge values will add. Restart.
Is the net charge of the distribution positive, negative, or zero?
