(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Which of the following is an accurate statement

1) The angular momentum of a moving particle depends on the specific origin with respect to which the angular momentum is calculated.

2) If the torque acting on a particle is zero about an arbitrary origin, then the angular momentum of the particle is also zero about that origin.

3) If the speed of a particle is constant, then the angular momentum of the particle about any specific origin must also be constant.

4) Consider a planet moving in a circular orbit about a star. Even if the planet is spinning it is not possible for its total angular momentum to be zero.

5) A particle moving in a straight line with constant speed necessarily has zero angular momentum.

2. Relevant equations

conservation of angular momentum and principles

3. The attempt at a solution

i am not sure whether which one is more accurate among 3,4 , could someone lead me on this.
