A bar magnet is oscillating in Earth's magnetic field with a period T. What happens to its period and motion if its mass is quadrupled?
  • a)
    Motion remains simple harmonic with time period = 4T
  • b)
    Motion remains simple harmonic and period remains nearly constant
  • c)
    Motion remains simple harmonic with time period = T/2
  • d)
    Motion remains simple harmonic with time period = 2T
Correct answer is option 'D'. Can you explain this answer?

A bar magnet is oscillating in Earths magnetic field with a period T. ...
Time period of the bar magnet in the external magnetic field is

If the mass of the bar magnet is increased 4 times, then the Moment of Inertia is also become 4 times so Time period will become twice but the motion remains simple harmonic.
