The vector is
Explanation:
The vector perpendicular to 2 vectors is calculated with the determinant (cross product)
where
Here, we have
Therefore,
Verification by doing 2 dot products
So,
Explanation:
Cross product of vectors A and B is perpendicular to each vector A and B.
We know that cross product of any two vectors yields a vector which is perpendicular to both vectors
Inserting given vectors we obtain
