Vector Product | MCQs

Explanation

The vector product (cross product) of two vectors gives a vector that is perpendicular to both original vectors.

Angular momentum is a vector product of position and linear momentum vectors.

Explanation

If A · B = 0, it means the vectors A and B are perpendicular.

The magnitude of the cross product is:

|A × B| = |A||B|sinθ

For perpendicular vectors, θ = 90°, so sin(90°) = 1

⇒ |A × B| = AB × 1 = AB
