Explanation / Answer

as long as the record player rotates without slipping, the formulav=r is always true. -where v is the linear velocity or a particle at a distance'r' from the axis of rotation -r is the distance from the axis of rotation - is the angular velocity, or the angle it moves through inone second. if 2 becomes 21, then by v2=r2 v2=21*r v2=2v1 That is, linear speed doubles, so option (A) iscorrect.
