Two identical magnetic dipoles of magnetic moments \( 1.0 \, \text{A} \cdot \text{m}^2 \) each, placed at a separation of \( 2\, \text{m} \) with their axis perpendicular to each other. The resultant magnetic field at a point midway between the dipoles is

The magnetic field at a point \( X \) on the axis of a small bar magnet is equal to the field at a point \( Y \) on the equator of the same magnet. The ratio of the distance of \( X \) and \( Y \) from the centre of the magnet is
