Question

If mass M and radius of solid sphere is R, then moment of Inertia about
diameter is :
​

Answer 1

Answer:

A solid sphere of mass M and radius R having moment of inertia I about its diameter is recast into a solid disc abut an axis passing the edge and perpendicular to the plane remains l. Then R and r are related as. From(i) and (ii), 25MR2=32Mr2⇒r=2√15R.
