The position vector of a point p is a vector that represents its position with respect to:
Correct answer: D. Origin of the coordinate system
- A. Another vector
- B. Centre of the earth
- C. Any point in space
- D. Origin of the coordinate system
Explanation
The position vector of a point P represents its position with respect to the origin of the coordinate system. It's a vector that points from the origin to the point P and describes the displacement needed to reach P from the origin.

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.
