1. There is a circular disk with a string wrapped around its center. We attached a mass to the string, and the force caused it to rotate. Now, the hypothetical question is "The hanging mass m is exerting a constant downward force of magnitude mg on our system. What would happen to the angular acceleration of our system if the hanging mass were removed and replaced by a constant downward force of equal magnitude, but with no associated mass?" 2. Relevant equationsNet Torque=Ia I=mr^2 sum of force=mg-T=ma 3. The attempt at a solution My first instinct was to say that nothing would change because the force would stay the same, but now I think that the angular acceleration would increase, because the lack of any associated mass would cause the inertia to decrease. Any help guys?
