Three point$-$like charges are placed at the following points on the $x-y$ system coordinates is fixed at $x=-1\mathrm{.}00cm,$

$q_2$ is fixed at $y=+1\mathrm{.}00cm,$ and $q_3$ is fixed at $x=+1\mathrm{.}00cm.$ Find the magnitude of the electric force on the charge $q_3.$

Let $q_1=+2\mathrm{.}80C,q_2=+3\mathrm{.}70C,$ and $q_3=-4\mathrm{.}20C.$
