We have two spheres, one of which is hollow and other is solid. They have identical mass and moment of inertia about its tangent. The ratio of their radii is given by

View answer and explanation

Correct option: C

\frac{\sqrt{21}}{5}

Option C (

\frac{\sqrt{21}}{5}

) is correct because the ratio of radii is derived by equating the moments of inertia about a tangent for a hollow and a solid sphere with identical mass.
