Under what circumstances would a nonzero vector lying in the xy plane have components that are equal in magnitude?
  1.This can never happen.
  2.Always. Components of vectors are always equal in just two dimensions.
  3.Only when the vector lies on the x- or y-axes (0, 90, 180, or 270).
  4.Only when the vector lies 45 from the x- or y-axes (45, 135, 225, or 315).

Question 2

Which of the following are reasonable values for the magnitude of a vector?
 
   (i) 0
   (ii) -1
   (iii) +1

  1.all of them
  2.(i) and (iii)
  3.(i) and (ii)
  4.(iii) only
