Which of the following is example of vector product of two vectors?
Correct answer: B. Angular momentum
- A. Linear momentum
- B. Angular momentum
- C. Force
- D. Electric flux
Explanation
Angular momentum is an example of a vector product of two vectors. The angular momentum of an object is given by the cross product of its position vector and linear momentum vector:L=r x pThis cross product yields a vector quantity, and angular momentum has both magnitude and direction.

About Vector Product
The vector product, or cross product, gives a vector perpendicular to two multiplying vectors, with magnitude AB sin θ and direction set by the right-hand rule. It covers properties such as anti-commutation, area from cross products, torque and angular momentum. Unlike the dot product, its result is a vector.
