The formula of unit vector is defined as_.
Correct answer: A. Dividing the vector by its magnitude
- A. Dividing the vector by its magnitude
- B. Dividing the magnitude by its vector
- C. Draw a cap on it
- D. None of these
Explanation
To find a unit vector with the same direction as a given vector, we divide the vector by its magnitude. For example, consider a vector v = (1, 4) which has a magnitude of |v|. If we divide each component of vector v by |v| we will get the unit vector uv which is in the same direction as v.

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.
