From a circular disc of radius R and mass 4m, a small disc of radius

\frac{R}{2}

is removed concentrically. The moment of inertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through its centre is

View answer and explanation

Correct option: B

\frac{{15}}{8}m{R^2}

Option B (15/8 mR²) is correct because it is the result of subtracting the moment of inertia of the removed disc from the original disc.
