Two small magnets `X` and `Y` of dipole moments `M_(1)` and `M_(2)` are fixed perpendicular to each other with their north poles in contact. This arrangement is placed on a floating body so as to move freely in earth's magnetic field as shown in figure then the ratio of magnetic moment is

Two identical bar magnets each of dipole moment p_m and length l are perpendicular to each other as shown in the figure . The dipole moment of the combination is :

If two identical bar magnets, each of length I, pole strength m and magnetic moment M are placed perpendicular to each other with their unlike poles in contact, the magnetic moment of the combination is

If two identical bar mangets, each of length 'I' , pole strength 'm' and magnetic moment 'M' are placed perpendicular to each other with their unlike poles in contact, the magnetic moment of the combination is

Two bar magnets M_(1)andM_(2) of equal lengths are such that the moment of the magnet M_(1) is double that of the magnet M_(2) . The magnets are fixed at right angle with each other such that their north poles are in the junction . If this combination is placed on a floating cork on water , find the angle of declination of the magnet M_(1) in equilibrium.
