A circular disc D 1 of mass M and radius R has two identical discs D 2 and D 3 of the same mass M and radius R attached rigidly at its opposite ends (see figure.) The moment of inertia of the system about the axis OO', passing through the centre of D v as shown in the figure, will be: 
A
B
MR 2
C
3 MR 2
D
MR 2
Text Solution
Verified by ExpertsThe correct answer is:
C
I 0 = (M.I. of A & B) + (M.I. of C)
I 0 = 
= 
= 3MR 2
