A hoop and a solid cylinder of same mass and radius are made of a permanent magnetic parallel to their respective magnetic moment parallel to their respective axes. But the magnetic moment of hoop is twice of solid cylinder. They are placed in a uniform magnetic field in such a manner that their magnetic moments make a small angle with the field. If the oscillation period of hoop and cylinder are `T_(h) and T_(c)` respectively, then
A
`T_(h) = T_(c)`
B
`T_(h) = 2T_(c)`
C
`T_(h) = 1.5 T_(c)`
D
`T_(h) = 0.5 T_(c)`
