AIIMS2004PhysicsRotational Motion
In an orbital motion, the angular momentum vector is
Options
- Aalong the radius vector
- Bparallel to the linear momentum
- Cin the orbital plane
- Dperpendicular to the orbital plane.
Correct answer
D. perpendicular to the orbital plane.
Step-by-step solution
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 right hand fist point in the direction of motion, the thumb is in the direction of L (angular momentum).
