A bar magnet is oscillating in the earths magnetic field with a period T. What happens to its period of motion, if its mass is quadrupled

(a)    Motion remains simple harmonic with new period = T/2.

(b)    Motion remains simple harmonic with new period =2T

(c)    Motion remains simple harmonic with new period = 4T

(d)    Motion remains simple harmonic and the period stays nearly constant
