VI3. 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 xy-plane. In equilibrium the angle 0 between their magnetic moments is such that .13, A NET DEC 2015 (a) tan = (b) tan 0 =0 3 (c) tan 6 = 3 QA4. A rototin (d) tan 6 = 1 fnif
