Area of the parallelogram in which the two adjacent sides are A and B is given by

Correct answer: A. AB sin θ

  • A. AB sin θ
  • B. Ab
  • C. AB cos θ
  • D. Zero

Explanation

If area of parallelogram formed by two vectors A and B is given by the magnitude of their cross product: Area of parallelogram = |A x B| So, the area of the parallelogram formed by two adjacent sides A and B is the magnitude of the cross product of these vectors.

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.
