Explanation:

The time period of the disc is 2π

(3r/2g)

We know that the time period of an object,

T=2π

(1/mgL)

where,

I= moment of inertia from the suspended point

L= distance of its centre from suspended point =r

we know that, the moment of inertia of disc about its centre =mr

2

/2

using parallel axis theoram the moment of inertia from a point in its periphery,

I=mr

2

+mr

2

/2=3mr

2

/2

putting the values in the above equation we get,

(3mr

2

/2mgr)

=2π

(3r/2g)

therefore, the time period of the disc is 2π

(3r/2g)
