Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): For a system of particles, the total angular momentum \( \mathbf{L} \) is equal to the vector sum of the angular momenta of individual particles. Reason (R): The linear momentum of an isolated single particle is always a conserved quantity. In the light of the above statements, choose the correct answer from the options given below:
Correct answer · Option 2
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
Explanation
Total angular momentum is defined by vector superposition \( \mathbf{L} = \sum \mathbf{l}_i \). Both statements are scientifically true, but the conservation of linear momentum of an isolated particle is not the reason for the vector addition definition.
