Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In many practical situations involving real bodies like wheels, tops, and planets, we can treat them as ideal rigid bodies. Reason (R): The deformations in such bodies during motion are negligible under ordinary forces. In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
