A disk is rotating about an axis through its center, perpendicular to its flat faces, as shown. The disk rotates at a constant angular speed. A certain point P is located on the disk's top face halfway between the axis and the edge of the disk. How would the motion of point P be different if it were moved outward closer to the disk's edge, while nothing else about the situation was changed? Which of these choices is correct? a) The angular speed of point P would decrease. b) The angular speed of point P would increase. c) The tangential speed of point P would decrease. d) The tangential speed of point P would increase.
