A vector whose magnitude is same as that of A, but opposite in direction is known as
Correct answer: B. Negative vector
- A. Null vector
- B. Negative vector
- C. Addition of vector
- D. Subtraction of vector
Explanation
Two vectors, having same magnitude but opposite direction are called negative vectors. Since they have equal magnitude but direction is opposite, one vector is referred to as the negative of the other one. However, two such vectors when added, they cancel each other and give us a zero vector.

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.
