In a right-handed Cartesian coordinate system, what is the vector cross product i x j?
Answer and explanation
Correct answer: D. k
- Step 1: By definition of right-hand triad basis vectors, i x j = k. Step 2. j x i = -k. Answer: k. Why not the others: -k is the opposite cross product j x i; 0 is the dot product i . j or cross product i x i; 1 is a scalar quantity rather than a vector.
