प्रश्न
If the angular momentum of a body is found to be zero about a point, is it necessary that it will also be zero about a different point?

उत्तर
No, angular momentum is dependent on the position vector of the particle, angle between the radius vector and the linear velocity of the particle. So, there may be finite angular momentum along any different point even if it is zero at a particular point.If angular momentum is zero along O' but finite along O.
