Two magnets of equal mass are joined at right angles to each other as shown in figure- \( 4.230 \). Magnet 1 has a magnetic moment three times that of magnet 2 . This arrangement is pivoted at center so that it is free to rotate in the horizontal plane. In equilibrium what angle will the magnet 1 subtend with the magnetic meridian :
Figure \( 4.230 \)
(A) \( \tan ^{-1}\left(\frac{1}{2}\right) \)
(B) \( \tan ^{-1}\left(\frac{1}{3}\right) \)
(C) \( \tan ^{-1}(\mathrm{~A}) \)
(D) \( 0^{\circ} \)
