Question

What is the unit vector perpendicular to 5j-12k=

Answer 1

Answer:

First, find a vector ai+bj+ck that is perpendicular to 8i+4j−6k. (Set the dot product of the two equal to 0 and solve. ...

Then divide that vector by its length to make it a unit vector. This unit vector will still be perpendicular to 8i+4j−6k .
