(A): When a rigid body rotates there is always a fixed axis or a fix point about which it has to perform the rotation.
(R): In a pure rotation different particle in a rigid body has different linear velocity.
(R): In a pure rotation different particle in a rigid body has different linear velocity.
View answer and explanation
Correct option: B
Both (A) and (R) are true and (R) is not the correct explanation of (A)
Option B (Both (A) and (R) are true and (R) is not the correct explanation of (A)) is correct because both the assertion and reason are true, but the reason doesn't explain why a rigid body rotates about a fixed axis.
