Two different disks of radii r 1 > r 2 are free to spin separately about an axis through the center and perpendicular to the plane of each disk. Both disks start from rest, and both undergo the same angular acceleration for the same length of time. Which disk will have the larger final angular velocity? (A) Disk 1 (B) Disk 2 (C) The disks will have the same angular velocity. (D) The answer depends on the mass of the disks.

The correct option is: (C) the disks will have the same angular velocity.
The magnitude of final angular velocity is given as: 236-1903_1.PNG
Therefore the magnitude of final angular velocity for disk1 is equal to the magnitude of final angular velocity for disk2, and (C) is the correct option.
