MethodSuperposition

Governing equation

V (r) = k i \sum \frac{q _{i}}{r _{i}}, k = 5000, \sum q_{i} = 0

Reading this result: The potential at any point is the superposition of every charge's k·q/r term, so overlapping fields simply add. Field lines run from high potential to low — out of + charges and into − charges — always crossing the equipotentials at right angles.
