For anti-parallel vectors angle is equal to ____________?
Correct answer: B. 180°
- A. 90°
- B. 180°
- C. 270°
- D. None of these
Explanation
Anti-parallel vectors lie along the same line but point in opposite directions, so the angle between them is 180°. The common mistake is choosing 90°, which applies to perpendicular vectors.

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
