Given is the arrangement of electric charges in the picture on the right.
The following force effects result:
$F_{01}=-5 N$
$F_{02}=-6 N$
$F_{03}=+3 N$

Calculate the magnitude of the resulting force.

Result

\begin{align*} |F_0| &= \sqrt{ (-0.418 N)^2 + (-9.264 N)^2 } = 9.274 N -> 9.3 N \\ \end{align*}
