The moment of inertia of a uniform circular disc is maximum about an axis perpendicular to the disc and passing through
  1. $B$
  2. $C$
  3. $D$
  4. $A$

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.
