Question

Find the magnitude of u x v and the unit vector parallel to u x v in the direction of u x v. u=6i-6j+7k, v=0

Answer 1

We have been given two vectors:

`u=6i-6j+7k` and
`v=0`.

Let us first find the cross product
`u * v`:

`u * v`=i(0)-j(0)+k(0) = 0i+0j+0k

Since the cross product turned out to be the null vector, therefore, we cannot find the unit vector parallel to
`u * v` in the direction of
`u * v` for the given scenario.
