A vector is a physical quantity which is completely specified by:
Correct answer: A. Both magnitude & direction
- A. Both magnitude & direction
- B. Magnitude only
- C. Direction only
- D. None of these
Explanation
A vector is a physical quantity that is completely specified by both its magnitude and its direction. Vectors have both numerical values (magnitude) and a specific orientation in space. Examples of vector quantities include displacement, velocity, force, and acceleration. The magnitude of a vector represents its size, and the direction indicates the path along which it acts or points.

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.
