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

A

`1:sqrt3`

B

`2:sqrt3`

C

`sqrt3:2`

D

`sqrt3:1`

Text Solution

Verified by Experts

The correct Answer is:
D
`M_(1)B Sin30^(@)=M_(2)B Sin60^(@)`
`(M_(1))/(M_(2))=(sqrt3)/(1)`
