| Directions: In the following questions, a statement of Assertion [A] is followed by a statement of Reason (R). Mark the correct choice as: |
| Assertion [A]: The magnetic field lines of the Earth resemble that of a magnetic dipole located at the centre of the Earth. |
| Reason (R): The axis of the dipole coincide with the axis of rotation of the Earth. |
A) Both Assertion [A] and Reason (R) are true and Reason (R) is the correct explanation of Assertion [A]
B) Both Assertion [A] and Reason (R) are true but Reason (R) is not the correct explanation of Assertion [A]
C) Assertion [A] is true but Reason (R) is false
D) Assertion [A] is false and Reason (R) is also false
Correct Answer: C
Solution :
(c) The magnetic field lines of the Earth resemble that of a hypothetical magnetic dipole located at the centre of the Earth. The axis of the dipole does not coincide with the axis of rotation of the Earth but is presently tilted by approximately \[11.3{}^\circ \] with respect to the later.
