Q.

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 a
Answer» D. both a x b and b x a
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.
