A disk mounted on an axle with an applied torque.
A disk mounted on an axle with an applied torque.
Three different disks are each mounted on a low-friction axle through their centers. A specific net torque is applied to each disk, and each disk has a specific rotational inertia, as shown in the table.

DiskNet TorqueRotational Inertia
1\(\tau_0\)\(I_0\)
2\(2\tau_0\)\(2I_0\)
3\(2\tau_0\)\(I_0\)

Which of the following correctly ranks the magnitudes of the angular accelerations, \(\alpha_1\), \(\alpha_2\), and \(\alpha_3\), of the three disks?
