  Consider the plane S formed by the dipole axis and the axis of Earth. If P be the point of intersection of the geographical and magnetic equators then the declination and dip angle at point P are:

A) \[0{}^\circ ,11.3{}^\circ \]                   

B)             \[11.3{}^\circ ,0{}^\circ \]

C)             \[11.3{}^\circ ,11.3{}^\circ \]               

D)             \[0{}^\circ ,0{}^\circ \]

Correct Answer: B

Solution :

(b) \[11.3{}^\circ ,0{}^\circ \] Refer to the adjacent figure given below. The point P is at the intersection of geographical equatpr (GE) and magnetic equator (ME) then at this point dip = 0° and declination \[=11.3{}^\circ \]
