$3.$ A charge $q_1$ experiences a net force of $0$ N and is located at the position shown. Using Coulomb's law, determine the value of the two charges and distance between $q_1$ and $q_2$ shown in the image. The charge of $q_1$ is $+3C$ and the $F_{21}=0\mathrm{.}08N$ to the left.

Which of the following correctly labels the unknown values?

A$.r_{12}=0\mathrm{.}8m$;$q_4=-1{10}^{-8}C$;$q_5=-2\mathrm{.}7{10}^{-5}C$

B$.r_{12}=0\mathrm{.}9m$;$q_4=2\mathrm{.}0{10}^{-8}C$;$q_5=-2\mathrm{.}0{10}^{-5}C$

C$.r_{12}=0\mathrm{.}4m$;$q_4=2\mathrm{.}0{10}^{-8}C$;$q_5=-1\mathrm{.}4{10}^{-5}C$

D$.$

$r_{12}=0\mathrm{.}3m$;$q_4=1\mathrm{.}9{10}^{-8}C$;$q_5=$

$-2\mathrm{.}0{10}^{-8}C$
