Consider two uniform discs of the same thickness and different radii 
and 
made of the same material. If the ratio of their moments of inertia 
and 
, respectively, about their axes is 
then the value of 
is :
A
B
C
2
D
4
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
be the density of the discs and 
is the thickness of discs.
Moment of inertia of disc is given by
(As 
and 
are same)
