# Problem: There is a force between two charged objects. To decrease the magnitude of the force, we can: A. Move the objects farther from each other or increase the charge on either of them. B. Move the objects farther from each other or reduce the charge on either of them. C. Move the objects closer to each other or increase the charge on either of them. D. Move the objects closer to each other or reduce the charge on either of them.

Electric force:

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

We see that force is directly proportional to q1q2 and inversely proportional to r2 (the square of the separation between the charges).
