Let two charges of equal magnitude Q but opposite sign be placed at 2a from each other.

Now a charge q₀ is placed midway between them.

The force experienced by it due the negative charge is

$F=\frac{1}{4\pi \varepsilon}\frac{Qq_{0}}{a^{2}}$ towards the negative charge

The force experienced by it due the positive charge is

$F=\frac{1}{4\pi \varepsilon}\frac{Qq_{0}}{a^{2}}$ away from the postive charge

So,the net force experienced by it will be

$F_{net}=2 \frac{1}{4\pi \varepsilon}\frac{Qq_{0}}{a^{2}}$ towards the negative charge.
