The resultant of two vectors is maximum when the angle between them is
- A. 90 degrees
- B. 180 degrees
- C. 120 degrees
- D. 0 degrees
Explanation
Parallel vectors add directly, so the resultant equals the sum of the magnitudes, which is the largest value achievable. At 180 degrees they oppose and the resultant is the difference, the minimum. Every intermediate angle gives a resultant between those two limits, which is the useful check on any answer.
