The sum and difference of two vectors are equal in magnitude. The angle between the vectors is
Correct answer: B. 90°
- A. 0°
- B. 90°
- C. 120°
- D. 180°
Explanation
The Explanation for this is as follows: application of simple formula. A.B = 0 when angle is 90 because cos90=0

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
