What is the condition for two non-zero vectors a and b to be negative of each other?
- A. a + b = 0
- B. a − b = 0
- C. a.b = 0
- D. a × b = 0
Answer: A) a + b = 0
Explanation: Vectors a and b are negative of each other if they have the same magnitude but opposite directions, meaning a = −b, which gives a + b = 0.
