Answer:
680.6 N
Step-by-step explanation:
The net force here is the resultant force. Taking that the two given forces act perpendicular to each other then the resultant is the hypotenuse. Therefore,
where d is the magnitude of downward force and s is the magnitude of the sideways force. Substituting 631 N for downward force and 255 N for sideways force then
![R=\sqrt {631^(2)+255^(2)}=680.5776958\approx 680.6 N](https://img.qammunity.org/2021/formulas/physics/high-school/jv8499o47otfgcwq7rbc4v50lc64x3c0ij.png)
Therefore, the magnitude of net force is equivalent to 680. 6 N
