• # question_answer A short magnetic needle is pivoted in a uniform magnetic field of strength 1 T. When another magnetic field of strength $\sqrt{3}\,T$ is applied to the needle in a perpendicular direction, the needle deflects through an angle q, where q is [KCET 1999] A)            30o B)            45o C)            90o D)            60o

In balance condition ${{B}_{2}}={{B}_{1}}\tan \theta$ $\Rightarrow \tan \theta =\frac{\sqrt{3}}{1}$ $\Rightarrow \theta ={{60}^{o}}$
