Electric field:

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

Electric potential:

$\overline{){\mathbf{V}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{\mathbf{r}}}$

a.

Net electric field, E = E1 + E2, where E1 is the electric field due to charge q1 and E2 is the electric field due to charge q2.

We're looking for a point where the electric field will be zero.
