Question

In an orbital motion, the angular momentum vector is :

• A. along the radius vector
• B. parallel to the linear momentum
• C. in the orbital plane
• D. perpendicular to the orbital plane

Answer 1

The correct option is D

perpendicular to the orbital plane

Angular momentum is a vector quantity whose direction is perpendicular to plane of revolution. It has been shown in the figure.


$\overrightarrow{L}=I\overrightarrow{W}$
$\overrightarrow{L}\parallel \overrightarrow{W}$
