Question

The number of unit vector perpendicular to a plane is​

Answer 1

Answer:

If a vector is perpendicular to two vectors in a plane, it must be perpendicular to the plane itself. As the cross product of two vectors produces a vector perpendicular to both, we will use the cross product of →v1 and →v2 to find a vector →u perpendicular to the plane containing them
