Frequency/Period of Oscillation

A solid disk of mass \(M\) and radius \(R\) is swung from a massless string of length \(R\) through a small angle as shown in Figure; Let \(R\)=5r.

Hint

Hint

×

The moment of inertia about the center of a solid disk is given by \(I_{\text{cm}} = \frac{1}{2} MR^2\), and the moment of inertia about a parallel axis a distance \(l\) away from the center of an object is given by \(I = Ml^2 + I_{\text{cm}}\).
