Now i got the answer to this problem but i am so confused at this one thing... how is it that the answer is 200 N of East and 600 N of west
the question is A force vector F1 points due east with a magnitude of 200 newtons and a second force F2 is added to F1. The resultant of the two vectors has a magnitude of 400 newtons and points along the East and west line. Find the magnitude and direction of F2 note that there are 2 answers. My question is I know the answers 2oo east and 6oo west but why north of east or north of west.

Actually in the answer book it tells me it is North.... I think it is weird though becuase of the fact that it has nothing about North.. in the question

I cant figur this out
The answer in your book must be wrong. You have an initial vector pointing along the eastwest line. If you add to it a vector with any component at all in the northsouth direction, the resultant cannot possibly be entirely along the eastwest line. I suspect the Doc is absolutely right.

simply put, there is 200 going "right" and 600 going "left" add 200 + (600) leads to a net of 400, and this 400 is along EW or as most would say xaxis..
