A uniform disc of radius 5cm and mass 200 g is fixed at its center to a metal wire, the order end of which is fixed with a clamp. The hanging disc is rotated about the wire through an angle and is released. If the disc makes torsional oscillations with time period 0.20s, then find torsional constant of the wire.
