Problem
A hoop and a solid cylinder of same mass and radius are made of a permanent magnetic material with their magnetic moment parallel to their respective axes. The magnetic moment of the hoop is twice that of the solid cylinder. They are placed in a uniform magnetic field such that their magnetic moments make a small angle with the field. If the oscillation periods of the hoop and cylinder are Th and Tc respectively, then:
(1) Th=Tc
(2) Th=2Tc
(3) Th=1.5Tc
(4) Th=0.5Tc
