Two Objects of Mass M₁ = 2m and M₂ =

question 31

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.
