Question

The resultant vector from the cross product of two vectors is _____________

(a) perpendicular to any one of the two vectors involved in cross product

(b) perpendicular to the plane containing both vectors

(c) parallel to to any one of the two vectors involved in cross product

(d) parallel to the plane containing both vectors

I got this question in my homework.

This question is from Computational Geometry topic in division Computational Geometry of Data Structures & Algorithms II

Answer 1

Right answer is (b) perpendicular to the plane containing both vectors

The best explanation: The resultant vector from the cross product of two vectors is perpendicular to the plane containing both vectors. In other words, it should be perpendicular to both the vectors involved in the cross product.
