Dip circle can be used to determine the angle of dip at a place . Dip circle consists of a magnetic needle free to rotate in a vertical plane . The end points of the needle move over a vertical circular scale . This arrangement can rotate about vertical axis . The angle rotated about vertical axis can be read from a horizontal scale .

If a dip circle is further rotated about vertical axis by `60^(@)` then the apparent dip at that position will be

A

The dip circle is in geographic meridian

B

The dip circle is in magnetic meridian

C

The dip circle is perpendicular to the magnetic meridian

D

The dip circle is perpendicular to the geographic meridian
