0The magnetic field at a point \( \mathrm{X} \) on the axis of a
\( \mathrm{P} \)
small bar magnet is equal to the field at a point \( \mathrm{Y} \) on the equator of the same magnet. The ratio of the distances of point \( \mathrm{X} \) and \( \mathrm{Y} \) from the center of the magnet is:-
(1) \( 2^{-3} \)
(2) \( 2^{-1 / 3} \)
(3) \( 2^{3} \)
(4) \( 2^{1 / 3} \)
