Configuration 1 | Configuration 2 | Configuration 3 | Configuration 4

Please wait for the animation to completely load.

Although electric fields can be quite complicated close to a charge distribution, they often become very simple at large distances (position is given in meters and electric field strength is given in newtons/coulomb). Restart.

1. What symmetries does each of these configurations have at large distances?
2. When possible, find an analytical expression for the field at large distances using Gauss's law for each configuration.

Note that each configuration contains either point charges or line charges (into and out of the screen), but not both. You can measure the electric field strength by click-dragging in the animation.
