A magnetic dipole is under the influence of two magnetic fields. The angle between the two field directions is `60^(@)` and one of the fields has a magnitude of `1.2xx10^(-2)T`. If the dipole comes to stable equilibrium at an angle of `15^(0)` with this field, what is the magnitude of the other field?

A

`1.39xx1010^(-3)T`

B

`2.39xx10^(-3)T`

C
