Two Objects of Mass M1 = 2m and M² =

question 15

Multiple Choice

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?

• A)m² will stop first because it has the larger initial angular velocity.
• B)m1 will stop first because it has the smaller radius.
• C)m² will stop first because the torque on it is greater.
• D)m1 will stop first because it has the smaller moment of inertia.
• E)Both objects will stop at the same time because the angular accelerations are equal.
