If x-component of a vector is 3 N and y-component is -3 N, then angle of the resultant vector with x-axis will be:
Correct answer: B. 315°
- A. 45°
- B. 315°
- C. 135°
- D. 225°
Explanation
The following is the solution: The correct answer is b)315 degrees. The angle of the resultant vector with the positive x-axis is −45∘ or− π/4 radians, and 315∘ is the equivalent angle in the standard position.

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.
