In an orbital motion, the angular momentum vector is :

Options

A. Along the radius vector
B. Parallel to the linear momentum
C. In the orbital plane
D. Perpendicular to the orbital plane.

Answer

D

Explanation

In orbital motion,the angular momentum vector is perpendicular to the plane In which the rotational motion take place and its sense is given by the right hand fist rule.When the fingers of light hand fist point in the direction of motion,the thumb is in the direction of L(Angular momentum)
