In a vacuum, two particles have charges of $q_1$ and $q_2,$ where $q_1=+3\mathrm{.}8C.$

They are separated by a distance of $0\mathrm{.}19$ m $,$ and particle $1$ experiences an attractive force of $3\mathrm{.}7$ N$.$

What is the value of $q_2,$ in C $,$ with its sign?

$-3\mathrm{.}9$

$5\mathrm{.}2$
