Total angular momentum of a system is found by adding the individual angular momenta:
AVectorially
BVertically
CVariably
DVisually
Answer & Solution
Correct answer: A. Vectorially
1. Angular momentum has direction as well as magnitude.
2. Simple arithmetic addition would lose the direction.
3. To get the total angular momentum we need to add vectorially the angular momenta of individual particles.
4. So the answer is vectorially.
