Per NCERT Table 6.1, the moment of inertia of a thin ROD of mass M and length L about an axis ⊥ to it through its midpoint is which?
AM L² / 2
BM L² / 3
CM L² / 4
DM L² / 12
Answer & Solution
Correct answer: D. M L² / 12
NCERT Table 6.1 (3): I_rod (⊥ at midpoint) = M L²/12. Through one end it would be ML²/3.
