What is the unit vector that is normal to the plane containing (3i + 4j - k)(3i+4j−k) and (2i+ j - 3k)(2i+j−3k)?
2 Answers
Explanation:
Taking the cross product of given vectors
Above vector will be normal to the given vectors hence the unit normal vector
hence the unit vector
The unit vector is
Explanation:
The vector normal to a plane containing
where
Here, we have
Therefore,
Verification by doing 2 dot products
So,
The unit vector is
