Two nonparallel vectors determine a plane. Relative to the plane determined by the position vector and velocity vector of a particle, in which direction is the angular momentum vector about the origin?
A)in the plane, but perpendicular to the velocity vector
B)in a direction dependent on the magnitudes of the velocity and position vectors
C)perpendicular to the plane
D)in the plane, but perpendicular to both the position vector and the velocity vector
E)in the plane, but perpendicular to the position vector

Question

Quizplus · Accepted Answer

The angular momentum vector is perpendicular to the plane determined by the position and velocity vectors, as it is the cross product of these two vectors.
