Bar Magnet|Solenoid As A Bar Magnet

Time period of a bar magnet oscillating in earth's magnetic field is T. Its magnetic moment is M. Now, a bar magnet of magnetic moment 2M is brought near it. The new time period will be

A bar magnet is oscillating in the earth's magnetic field with a time period T . If the mass is quadrupled, then its time period will be:
