Question $2$: $(2$ points$)$

A $2\mathrm{.}0-C$ point charge is $15$ m from a second point charge, and the electric force on one of them due to the other is $1\mathrm{.}0$ N $.$ What is the magnitude of the second charge?

$)=\frac{1}{4}{}_0=(8\mathrm{.}99{10}^9(N)*\frac{m^2}{C^2}$

A$)12\mathrm{.}5$ nC

B$)5\mathrm{.}0$ C

C$)12\mathrm{.}5C$

D$)0\mathrm{.}025$ C

E$)12\mathrm{.}5$ C
