If Bx and By are the magnitudes of the components and iˆ and j ˆ are the unit vectors along x and y axis, then we can write:
Correct answer: A. Option A
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
If Bx and By are the horizontal and vertical components of vector B respectively, then vector B can be expressed as: B = Bxi^ + Byj^ Here, i is the unit vector along x-axis and j is the unit vector along y-axis. This representation breaks down the vector into its horizontal and vertical components.

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.
