A vector whose tail lies at the origin of the coordinates and whose head lies at the position of point 'P' in space, known as
Correct answer: C. Position vector
- A. Free vector
- B. Fixed vector
- C. Position vector
- D. Parallel vector
Explanation
A vector whose tail lies at the origin of the coordinates and whose head lies at the position of point 'P' in space is often referred to as the position vector of point 'P' with respect to the origin. The position vector points from the origin to the point 'P' and represents the displacement from the origin to 'P'.

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.
