If I1 is the moment of inertia of a thin rod about an axis passing through its end and perpendicular to its length and I2 is the moment of inertia of the ring formed by bending the rod about its diameter, then
A
I1 : I2 = π2
B
I1 : I2 = 4π2 : 3
C
I1 : I2 = π2 : 4
D
I1 : I2 = 8π2 : 3
Answer
I1 : I2 = 8π2 : 3
Explanation
Solution
I1 = , I2 =
=
(4) is the correct.
