Expert Answer
The acceleration depends on the moment of inertia.
Moment of inertia for the given object,
I ( ring) = MR2
I (solid sphere) = 2/5 MR2
I ( solid cyllinder) = 1/2 MR2
Heigher is the moment of inertia lower is its acceleration.
I (solid sphere) < I ( solid cyllinder) < I ( ring)
Ring will reach to the ground first.
I know that the higher the moment of inertia the lower the acceleration
