One solid sphere 
and another hollow sphere 
are of same mass and same outer radius. Their moments of inertia about their diameters are respectively, 
and 
such that
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Let same mass and same outer radii of solid sphere and hollow sphere be 
and 
,
respectively. The moment of inertia of solid sphere 
about its diameter,
… (i)
The moment of inertia of hollow sphere (spherical shell)
about its diameter, 
… (ii)
From Eqs. (i) and (ii), we get
