Task 1.2.2 Variation: Multiple Forces on a Charge II (exam task, ca 8% of a 60 minute exam, WS2020)
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.
\begin{align*}
|F_0| &= \sqrt{ (-0.418 ~N)^2 + (-9.264 ~N)^2 } = 9.274 ~N \rightarrow 9.3 ~N \\
\end{align*}
