The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance $d$ between the charges is the same. The magnitude of the charges is $|q|=6\mathrm{.}3C,$ and the distance between them is $d=3\mathrm{.}4mm.$ Determine the magnitude of the net force on charge $2$ for each of the three drawings.
