Problem 22.1: Like and unlike charges

Please wait for the animation to completely load.

Five charged objects are shown on the screen along with vectors representing the forces on each object. You can click-drag on any object to change its position (position is given in meters). Restart.

  1. Find two objects that repel each other and place them aside. Can you find any object that is attracted to one of these objects and repelled by the other? What does this observation tell you?
  2. How many charges are alike?
