A vector lying along x-axis has
Correct answer: D. None of these
- A. Its x and z components zero
- B. Its y-component equal to zero
- C. Its x and y components equal to zero
- D. None of these
Explanation
The Explanation for this question is as follows: A vector lying along the x-axis has its tail at the origin and its head pointing in the positive x-direction. The direction of the vector is specified by the axis along which it lies. In this case, a vector along the x-axis is typically represented as i in vector notation. The unit vector i has a magnitude of 1 and points in the positive x-direction. Mathematically, the vector along the x-axis can be expressed as: A=A⋅i where A is the magnitude of the vector (which can be any real number). The vector has all x,y,z components present.

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.
