A force vector F1 points due east and has a magnitude of 200N. A second force F2 is added to F1. The resultant of the two vectors has a magnitude of 400N and points along the east/west line. Find the magnitude and direction of F2.(adsbygoogle = window.adsbygoogle || []).push({});

i really don't know what equation I would use to solve this problem.
