Draw and label a force diagram for the forces on each of the three charges. Then calculate the net force $($magnitude and direction$)$ on each charge. $[$magnitudes are $2\mathrm{.}93{10}^{-7}N,6\mathrm{.}68{10}^{-7}N,3\mathrm{.}75{10}^{-7}N,$ be sure to also indicate direction $($left or right is fine for this one instead of a number angle.$))$

$0$longleftrightarrow,$2\mathrm{.}1nm,0$longleftrightarrow$0$

$q_1=-84e$

$q_2=56e$

$q_3=21e$
