Let us name three perpendicular directions as right, up$,$ and toward you as you might name them when you are facing a television screen that lies in a vertical plane. Unit vectors for these directions are r$,,$ and t$$ respectively. Consider the quantity $(32$t$).$

$($a$)$ What is the magnitude of this vector?

$6320$

$($b$)$ What is the direction of this vector?
