The moment of inertia of a disc, of mass $M$ and radius $R$, about an axis which is a tangent and parallel to its diameter is

• A

  $\frac{1}{2} M R^2$
• B

  $\frac{3}{4} M R^2$
• C

  $\frac{1}{4} M R^2$
• Correct answer
  D

  $\frac{5}{4} M R^2$

Solution

The moment of inertia of a disc about axis which is a tangent and parallel to its diameter is $\frac{5}{4} M R^2$

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