Moment of inertia of a uniform annular disc of internal radius rr and external radis RR and mass MM about an axis through its centre and perpendicular to its plane is
View answer and explanation
Correct option: B
12M(R2+r2)\frac{1}{2} M\left(R^2+r^2\right)
Option B (12M(R2+r2)\frac{1}{2} M(R^2+r^2)) is correct because it represents the moment of inertia of an annular disc about an axis through its center and perpendicular to its plane.
