If two vectors lie in xy-plane, their cross product lies
Correct answer: C. Along perpendicular to that plane
- A. In the same plane
- B. Adjacent plane
- C. Along perpendicular to that plane
- D. Parallel to the plane
Explanation
The Explanation for this question is as follows: Point index finger in the x-plane, middle finger in the y-plane, your thumb will point in the direction of the cross product of the two vectors in xy-plane.

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.
