A rod is placed along the line 
with its centre at origin. The moment of inertia of the rod is maximum about
A
-axis
B
-axis C
-axis
D
Data insufficient
Text Solution
Verified by ExpertsThe correct answer is:
C
The given situation of rod is shown below.
Suppose a mass particle situated at point 
.
Hence, distance of mass particle from 
-axis 
,
distance of mass particle from 
-axis 
and distance of mass particle from 
-axis, 
Clearly, 
Since, moment of inertia, 
(distance) 
.
Hence, moment of inertia of the rod is maximum about 
-axis.
