Question #348813

A force of magnitude 100N is directed westward and a second force of magnitude 200N is directed 60 degrees north of east. Find the magnitude and direction of the third force that when added to the first 2 forces gives a resultant whose magnitude is 150N and points 30 degrees north of east?

Expert's answer

"\\vec F_3=\\vec F-\\vec F_1-\\vec F_2,"

"F_3=250~N,"

"\\varphi=-60\u00b0."
