New page
From the previous part we have that

<math>\mathbf{F}4=-\mathbf{F}1-\mathbf{F}2-\mathbf{F}3=-292\mathbf{i}-62\mathbf{j}\ \text{N}</math>

Thus the magnitude <math>Q</math> is given by

<math>Q{}^{2}={{\left( -292 \right)}^{2}}+{{\left( -62 \right)}^{2}}=85300+3840=89140</math>

or

<math>Q=299 \text{ N}</math>
