A dip circle is so set that its needle moves freely in the magnetic meridian. In this position, the angle of dip is \[40{}^\circ \]. Now the dip circle is rotated so that the plane in which the needle moves makes an angle of \[30{}^\circ \] with the magnetic meridian. In this position, the needle will dip by an angle

• A. \[{{40}^{o}}\]
• B. \[30{}^\circ \]
• C. more than \[40{}^\circ \]
• D. less than \[{{40}^{o}}\]
