Physics - SHM Question with Solution | TestHub

A disk of mass $M=2\mathrm{kg}$ and radius $R=5\mathrm{m}$ is pivoted at the centre. The disk lies in the vertical plane and is free to rotate about the pivot (see figure). A particle of mass $m=1\mathrm{kg}$ is attached to the periphery of the disk as shown in the figure. The time period of small oscillation of the system is: [Taking : $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ ]
