1.	If mass M and radius of solid sphere is R, then moment of Inertia aboutdiameter is :(A) 2/3MR^2(B) 2/5MR^2(c) 3/5MR^2(d) 7/5MR^2
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.
