Which of the following has the highest moment of inertia when each of them has the same mass and the same radius?
Text Solution
Verified by ExpertsThe correct answer is:
C
: Let M and R be the mass and radius respectively. Moment ofinertia of a ring about any of its diameter is. 
Moment of inertia of a disc about any of its diameter is
Moment of inertia of a hollow sphere about any of its diameter is.
Moment of inertia of a solid sphere about any of its diameter is.
Thus, 
is largest.
