Let we have a vector F, then its horizontal component is written as:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The horizontal component of a vector F is given by Fx = |F|cosθ , where |F| is the magnitude of the vector F and θ is the angle between the vector and the positive x-axis. If i is unit vector along the x-axis, then Fx = |F|cosθi^

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.
