STEP 1
Find the net force by finding the sum of the individual forces for their respective x and y components
When we sum the above, we have the net force as:

STEP 2:
We find the magnitude of the net force by using the formula below:
![\begin{gathered} M\text{agnitude of net force = }\sqrt[]{x^2+y^2} \\ =\text{ }\sqrt[]{(-5)^2+4^2} \\ =\sqrt[]{25+16} \\ =\sqrt[]{41} \\ =6.4\text{ newtons} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/j6io8hj496dcndwgiisttqyf77qjn9c7wr.png)
In conclusion, the magnitude of the net force is 6.4 newtons
