Coulomb's Charge Graphs

These calculators can be used to generate data using **charge**, **radius** and **force**.

The calculators on this page rovolve around a single equation.
That equation is rearranged in terms of the variables in it and there is
a section per version of the equation. Each section contains a series of graphs that
each vary one of the other variables in the equation.

Calculate the **force** given two **charge**es and a **radius**.

F = kQq/r^{2}

Force with changing charge1

Force with changing charge2

Force with changing radius

Calculate the first **charge** given the second **charge**, **force** and **radius**.
