Assumptions - Electric Field Due To Two Point Charges

The applet simulates the electric field and the equipotential lines (Curves) accompanying two electric point charges.

The applet makes the following assumptions:

A consequence of these assumptions is that, for points outside the source objects, the source objects behave like point charges.

The applet does not permit field points inside the finite source objects. Its purpose is to simulate the electric field due to a pair of point charges.
