Charge Field Graphs

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

The charge field, as expressed by these equations, is the surface charge vector of a body with the given radius and density. The values are negative relative to the solo gravity vector for the body. Where solo gravity points in, towards the body, the charge vector points out.

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 **charge** given the **density** and **radius**.

e = E_{e}d^{2}r^{3}/E_{d}^{2}E_{r}^{3}
