Calculate the vector cross product L = r × p.

1. L = r × p
2. L = p × r
3. L = r · p
4. L = p · r

Correct answer: L = r × p

Solution

The vector cross product is defined as L = r × p, where r is the position vector and p is the momentum vector. This operation results in a vector perpendicular to both r and p.
