Problem 25.4: Determine the unknown charge

Please wait for the animation to completely load.

The charges shown are given in units of 10-10 C (position is given in meters and electric potential is given in volts). Restart. You can measure the electric potential by dragging the test charge around.

Determine the charge of the unknown charge for the following distributions:

  1. Two charges.
  2. Three charges.
  3. Four charges.
