Moment of inertia of a uniform annular disc of internal radius

r

and external radis

R

and mass

M

about an axis through its centre and perpendicular to its plane is

View answer and explanation

Correct option: B

\frac{1}{2} M\left(R^2+r^2\right)

Option B (

\frac{1}{2} M(R^2+r^2)

) is correct because it's the standard formula for the moment of inertia of an annular disc.
