Position vector of point in xy-plane is given by:
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The position vector of a point in the xy-plane is typically given by the coordinates (x, y), where x represents the horizontal distance and y represents the vertical distance from the origin. So, the position vector can be written as r = xi + yj, where i and j are the unit vectors along the x and y axes, respectively.

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.
