Q. The moment of inertia of a uniform circular disc is maximum about an axis perpendicular to the disc and passing throughPhysics Question Image

AIPMTAIPMT 2012System of Particles and Rotational Motion

Solution:

According to the theorem of parallel axes,
$I=I_{CM}+Ma^2$
As $a$ is maximum for point $B$.
Therefore $I$ is maximum about $B$.
