Problem 24.11: Charge on capacitor using Gauss's law

Please wait for the animation to completely load.

Each "charge" represents a long charged rod that extends into and out of the screen (position is given in centimeters and electric field strength is given in newtons/coulomb). Restart.

  1. Add the top plate of the capacitor. Measure the electric field close to the top plate and then use Gauss's law to find the charge/area on the plate.
  2. Do the same for the bottom plate.
  3. What is the field near the center of the completed capacitor?
