#### Question

Show that each of the given three vectors is a unit vector:

`1/7 (2hati + 3hatj + 6hatj), 1/7(3hati - 6hatj + 2hatk), 1/7(6hati + 2hatj - 3hatk)`

Also, show that they are mutually perpendicular to each other.

#### Solution

Hence, the given three vectors are mutually perpendicular to each other.

Is there an error in this question or solution?
