4 Consider an object on a rotating disk a distance r from its center, held in place on the disk by static friction. Which ofthe following statements is not true concerning this object?O If the angular speed is constant, the object must have constant tangential speed.O If the angular speed is constant, the object is not accelerated.O The object has a tangential acceleration only if the disk has an angular acceleration.O If the disk has an angular acceleration, the object has both a centripetal acceleration and a tangential acceleration.O The object always has a centripetal acceleration except when the angular speed is zero.

We need to comment on which of the statements is not true regarding the object on the disk.
