Physics - Rotation Question with Solution | TestHub

A solid sphere of mass ' $M$ ' and radius ' $R$ ' is rotating about its diameter. A solid cylinder of same mass and radius is also rotating about its geometrical $1:3$ axis with an angular speed twice that of the sphere. The ratio of their kinetic energies of rotation ( ${\mathrm{K}}_{\text{sphere }}$ to ${\mathrm{K}}_{\text{cylinder }}$ ) will be
