A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through $180^o$ to deflect the magnet by $30^o$ from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through $ 270^o$ to deflect the magnet $30^o$ from magnetic meridian. The ratio of magnetic moments of magnets is

A dip circle is adjusted so that its needle moves freely in the magnetic meridian. In this position, the angle of dip is $40°$. Now the dip circle is rotated so that the plane in which the needle moves makes an angle of $30°$ with the magnetic meridian. In this position the needle will dip by an angle
