Two objects of mass m1 = 2m and m2 = m move around a rotation axis A in parallel circles of radii r1 = r and r2 = 2r with equal tangential speeds. As they rotate, forces of equal magnitude are applied opposite to their velocities to stop them. Which statement is correct?



◦
m2 will stop first because it has the larger initial angular velocity.

◦
m1 will stop first because it has the smaller radius.

◦
m2 will stop first because the torque on it is greater.

◦
m1 will stop first because it has the smaller moment of inertia.

◦
Both objects will stop at the same time because the angular accelerations are equal.
