Be sure to review Examples $21\mathrm{.}3$ and $21\mathrm{.}4($Section

$21\mathrm{.}3)$ before attempting these problems.

Charge $q_1=+5\mathrm{.}60nC$ is on the $x-$axis at $x=0$ and an unknown charge $q_2$ is on the $x-$axis at $x=-4\mathrm{.}00cm.$ The total electric

force that $q_1$ and $q_2$ exert on a third charge $q_3=+2\mathrm{.}00nC$ on the $x-$axis at $x=4\mathrm{.}00cm$ is in the $+x-$direction and has

magnitude $82\mathrm{.}0N.$ Find the $x-$component of the force that $q_1$ exerts on $q_3.$

Express your answer in micronewtons.
