STATEMENT-1 : Time period of a physical pendulum is independent of mass of the body. STATEMENT-2 : Time period of a torsional pendulum is 2pi sqrt((l)/(k)) where, l= moment of inertia and k= Torsional constant. STATEMENT-3 : S.H.M. is an example of non-uniform motion.

The moment of inertia of the disc used in a torsional pendulum about the suspension wire is 0.2kg-m^2 . It oscillates with a period of 2s. Asnother disc is placed over the first one and time period of the system becomes 2.5s. Find the moment of inertia of the second disc about the wire.
