Q67 / 120 · NEET 2012 (Mains) · Physics

The moment of inertia of a uniform circular disc is maximum about an axis perpendicular to the disc and passing through

Correct answer
A
$B$
B
$C$
C
$D$
D
$A$

Solution

Moment of inertia \(\mathrm{I}=\mathrm{I}_{\mathrm{cm}}+\mathrm{md}^2\) d is maximum for B \(\therefore \mathrm{I}\) is maximum for B.

Hence, the correct answer is option: 'A'.
