Answer
See the explanation below.
Work Step by Step
The vector in component form can be expressed as:
$v =\lt v_{1}, v_{2}, v_{3}\gt $
The magnitude of the vector $u$ shows its length and is given by:
$|u|=\sqrt{u_{1}^{2}+u_{2}^{2}+u_{3}^{2}}$
and the direction of the vector is known as the unit vector $u$ (having vector of magnitude 1 in the direction of $v$):
$u=\dfrac{v}{|v|}=\dfrac{1}{\sqrt{v_{1}^{2}+v_{2}^{2}+v_{3}^{2}}}\cdot\ \lt v_{1}, v_{2}, v_{3} \gt$
