Question

What is the angular momentum vector in an orbital motion?(a) The vector is perpendicular to the orbital plane
(b) The vector is along the radius vector
(c) The vector is parallel to the linear momentum
(d) The vector is in the orbital plane​

Answer 1

Answer:

Therefore, the direction of the angular momentum vector in orbital motion is perpendicular to the orbital plane. So, the correct answer is option (D). Note: The direction of orbital angular momentum plays a very important role when dealing with the motion of electrons in the nucleus.
