Diversion: A random rule for your consideration  
Coulomb's law - The force between two point charges is proportional to the algebraic product of their respective charges as well as proportional to the inverse square of the distance between them: F = 1/(4 pi epsilon0) (q Q/r2) e, where q and Q are the strengths of the two charges, r is the distance between the two, and e is a unit vector directed from the test charge to the second.
