Question 1 of 21 · 5.0 marks

A small magnetic needle is kept at

(0, 0)

with its moment along the

x

-axis. Another small magnetic needle is at the point

(1, 1)

and is free to rotate in the

x y

- plane. In equilibrium the angle

θ

between their magnetic moments is such that

1 $t an θ = \frac{1}{3}$
2 $t an θ = 0$
3 $t an θ = 3$
4 $t an θ = 1$

Correct answer: Option 3
