A dip circle is adjusted so that its needle moves freely in the magnetic meridian. In this position, the angle of dip ia `45^(@)`. 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
