Per NCERT Table 6.1, the moment of inertia of a thin RING of mass M and radius R about an axis ⊥ to its plane through its centre is which?
A(1/2) M R²
B(2/3) M R²
CM R²
D(2/5) M R²
Answer & Solution
Correct answer: C. M R²
NCERT Table 6.1 (1): I_ring (axis ⊥ plane, through centre) = M R². All mass lies at distance R from axis.
