###### FREE Expert Solution

Remember that electron is negatively charged while the proton is positively charged.

There will be a force of attraction between the two charged particles.

From Coulomb's law:

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