Question

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

• A. $A$
• B. $B$
• C. $C$
• D. $O$

Answer 1

The correct option is B $B$

We know from the parallel axis theorem,
$I=I_{COM}+M{d}^2$

Here, $I_{COM}$ & $M$ is same for all the points and only $d$ is varying. So the axis which is having more distance from COM will have more MOI.
Therefore, maximum MOI is about the axis passing through point B.
