Exploration 22.6: Run Coulomb's Gauntlet

Please wait for the animation to completely load.

A positive test charge is shown in the animation. You can add positive and/or negative charges. All charges are added to the middle of the animation, so you must drag each newly added charge to a new location. When you push "play," the test charge will move under the influence of the forces from the other charges. Restart.

Move the charges so that the test charge can make it from its starting place to the finish line without hitting a wall.

  1. Describe your technique.
  2. What is it about the Coulomb force that makes this so difficult? Explain.
