A magnetic dipole is acted upon by two magnetic fields which are inclined to each other at an angle of `75^(@)`. One of the fields has a magnitude of 15 mT. The dipole attains stable equilibrium at an angle of `30^(@)` with this field. The magnitude of the other field (in mT) is close to:

Options

A. `1.5 xx 10^(-2) T `
B. `1.5 sqrt(2) xx 10^(-2) T `
C. `(1.5)/( sqrt(2)) xx 10^(-2) T `
D. `(1.5 ) 2sqrt(2)) xx 10^(-2 ) T `
