1 of 3Boxes A and B are sitting on the platform of a merry-go-round, held by static friction. B is twice as far from the axis of rotation as A. The merry-go-round is accelerating in an angular sense. The magnitude of the centripetal acceleration experienced by B is
1. Zero.2. Half that of A.3. Equal to that of A.4. Twice that of A.5. Four times that of A.
