Moment Inertia OF RING:

  • Now, for the axis which is tangential and perpendicular to ring , we need to apply PARALLEL AXES THEOREM.

 \rm MI = m {r}^{2}  + m {d}^{2}

  • Here d = radius (r)

 \rm \implies MI = m {r}^{2}  + m {r}^{2}

 \rm \implies MI = 2m {r}^{2}

 \rm \implies MI = 2 \times  \dfrac{500}{1000} \times   {(0.5)}^{2}

 \rm \implies MI = 2 \times  0.5 \times  0.25

 \rm \implies MI =  0.25 \: kg {m}^{2}

So, Moment of Inertia along given axis is 0.25 kgm².
