Three charges are located as shown in the figure, with values q$1=3\mathrm{.}7\backslash$times $10-16$ C$,$ q$2=-1\mathrm{.}9\backslash$times $10-16$ C$,$ q$3=6\mathrm{.}75\backslash$times $10-16$ C$.$ The charges are separated by d$1=2\mathrm{.}2\backslash$times $10-6$ m and d$2=4\mathrm{.}7\backslash$times $10-6$ m$.$ What is the force of q$3$ on q$1$ in the y direction, Fy$?$ Give your answer in newtons.
