6.In Tan A position, a short bar magnet placed at a distance of 30 cm from the mid-point of the needle produces a deflection of 45°. When another magnet is placed at the same distance, it produces a deflection of 30°. Then the ratio of their magnetic moments is

1.1
1.72
5.1732
1.732

7.In Tan B position of null deflection method of comparing the magnetic moments of bar magnets, the ratio of their moments is given by

M1/M2 = (d12+l12)3/2/ (d22+l22)3/2
M1/M2 = (d12-l12)3/2/ (d22-l22)3/2
M1/M2 = (d22+l22)3/2/ (d12+l12)3/2
M1/M2 = (d22-l22)3/2/ (d12-l12)3/2
