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