1.	Which of the following operation will give a vector that is perpendicular to both vectors a and b?(a) a x b(b) a.b(c) b x a(d) both a x b and b x aI have been asked this question in an international level competition.My query is from Computational Geometry in portion Computational Geometry of Data Structures & Algorithms II
Answer» Right choice is (d) both a X b and b x a Best EXPLANATION: The resultant VECTOR from the CROSS product of two VECTORS is perpendicular to the plane containing both vectors. So both a x b and b x a will give a vector that is perpendicular to both vectors a and b.
