Question

Consider the two vectors M = (a, b) = aˆi+bˆi and N = (c,d) = cˆi+dˆi, where a = 4, b = 4, c = 3, and d =3. a and c represent the x-displacement and b and d represent they- displacement in a Cartesian xy co-ordinate system.

a) What is the magnitude of the vector product M × M ?
b) What is the magnitude of the vector product M× N ?

c) What is the direction of the vector product M× N?
   1. in the yz plane, but not along y or z
   2. along the x-axis
   3. none of these since its direction cannot bedetermined
   4. in the xz plane, but not along x or z
   5. in the xy plane, but not along x or y
   6. along the z-axis
   7. along the y-axis c) What is the direction of the vector product M× N?
   1. in the yz plane, but not along y or z
   2. along the x-axis
   3. none of these since its direction cannot bedetermined
   4. in the xz plane, but not along x or z
