We are required to determine the ratio F_{E}:F_{G}.

F_{E} is given by coulomb's law:

$\overline{){{\mathbf{F}}}_{{\mathbf{E}}}{\mathbf{=}}\frac{\mathbf{k}{\mathbf{q}}_{\mathbf{1}}{\mathbf{q}}_{\mathbf{2}}}{{\mathbf{r}}^{\mathbf{2}}}}$

The ratio of the electric force between two electrons to the gravitational force between them is of the order of

A. 10^{42}

B. 10^{40}

C. 10^{36}

D. 10^{32}
