Question

Find a unit vector perpendicular to A = (î+ ĵ – Îk) and B = (
2i + j- 3k).
(Hints. One method to find the unit vector C perpendicular to A and B will be to use the fact that the
cross product is perpendicular to both vectors A and B, but keep in mind that the magnitude of the unit
vector is one.
There is another method which is a little bit longer by using the fact that the dot product AC=0 and BC=0
where C is the unit vector )
