Identify the incorrect property of the cross product of vectors.
- A. a × b = −(b × a)
- B. a × a = 0
- C. a × (b + c) = a × b + a × c
- D. (a × b) × c = a × (b × c)
Answer: D) (a × b) × c = a × (b × c)
Explanation: The cross product is NOT associative. Therefore, (a × b) × c ≠ a × (b × c) in general.
