Answer 1


Because each vector has the same magnitude, fig (1) is most obviously directed downward. return to top

Answer 2


If this vector's magnitude was greater than that of fig (1), it would have a larger downward component. But all of the magnitudes are equal, so it doesn't. return to top

Answer 3


Again, this vector is not the one that points most directly downward. In fact this vector has no downward component. return to top

Answer 4


This is the least likely answer; the vector points upward. return to top

What's this question really asking?

Which vector has the largest downward component?
Remember component means part. return to top
