Question

State the components of a unit vector that is perpendicular to the vector v= (5,2,-1)

Answer 1

Given the following vector:

$v=(5,2,-1)$

We will find a unit vector that will be perpendicular to the given vector

As we know, the perpendicular vectors have a dot product = 0

Let the perpendicular vector = w = (x,y,z)

So, we will write the equation of the dot product as follows:
