Question:
In Tan A position of null deflection method of comparing the magnetic moments of bar magnets the ratio of their moments is given by

1.M1/M2 = (d12-l12)2 d2/ (d12-l22)2 d1

2.M1/M2 = (d12-l12)2 d1/ (d12-l22)2 d2

3.M1/M2 = (d12+l12)2 d1/ (d12+l22)2 d2

4.M1/M2 = (d12+l12)2 d2/ (d22-l22)2 d1
