A
dimensions and mass of needle
B
dipole moment of needle
C
horizontal component of Earth's field
D
length of suspension fibre
Correct Answer
length of suspension fibre
Detailed Explanation
the period of oscillation of a freely suspended magnetic needle does not depend on the length of the suspension fiber. This is because the period of oscillation is determined by the moment of inertia and the magnetic field, and not the length of the suspension fiber.
