AP and TS EAMCET Engineering Model Paper 12

A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of the wire is rotated through 180° to deflect the magnet is by 30° from magnetic meridian .Now this magnet is replaced by another magnet. Now the upper end of the wire is rotated through 270° to deflect the magnet 30° from the magnetic meridian .The ratio of magnetic moments of the two magnets is
