    Developed in the late 1700s by Frenchman Charles Augustin de Coulomb it describes the electrostatic forces between electric charges. There are two main equations deriving from the Law; the Scalar Form and the Vector Form. In a scenario where direction is needed, the Scalar Form is required.

    [size=+1]Scalar Form[/size]
    F=[(q1q2)/(r^2)]Ke

    Where q1=charge
    q2=second charge
    r=distance between the two charges
    Ke=8.9876x10^9 Nm^2C^-2

    I feel it is unnecessary to include to Vector Form of the equation as it is pretty complicated

    Someone needs to add a key that states what each variable is and the units of each variable.

    A little better. "r" must be meters. But what about units of charge and "C"? Does Ke have a name? (It's been a long time since I had Physics lab or Circuits I. Gotta keep your units straight.)
