A hot black body emits the energy at the rate of `16 J m^(-2) s^(-1)` and its most intense radiation corresponds to suspension is vertically above the centre of the sphere. A torque of 0.10 N-m is required to rotate the sphere through an angle of `1.0` rad and then maintain the orientation. If the sphere is then released, its time period of the oscillation will be :
