| ASSERTION: At neutral point, a compass needle point out in any arbitrary direction. |
| REASON: Magnetic field of earth is balanced by field due to magnets at the neutral points. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
A neutral point in the magnetic field of a bar magnet is that point, where the field due to magnet is completely neutralized by the horizontal component of earth's magnetic field. The net horizontal field is zero at such a point. If a compass needle is placed at such a point, it can stay in any position.
