Question

Two magnets A and B are identical and these are arranged as shown. Their lengths are negligible in comparison to separation between them. A magnetic needle is placed between the magnets at point P and it gets deflected through an angle $\theta$. The ratio of distances $d_1$ and $d_2$ will be :

• A. $(2cot\theta {)}^{1/3}$
• B. $(2tan\theta {)}^{1/3}$
• C. $\left(2cot\theta \right)$
• D. $(2tan\theta {)}^{-1/3}$

Answer 1
