Assertion (A) : Neutral points are the points at which two magnetic fields are equal in magnitude and in the same direction.

Reason (R) : The net magnetic field at a neutral point is zero.

1. both A and R are true and R is the correct explanation of A
2. both A and R are true and R is not the correct explanation of A
3. assertion is false but reason is true
4. assertion is true but reason is false

assertion is false but reason is true

Explanation

Assertion (A) is false because neutral points are locations where the magnetic fields from two sources (e.g., a bar magnet and Earth's field) are equal in magnitude but opposite in direction, so they cancel out.

Reason (R) is true because that's the definition of a neutral point i.e., the point at which two magnetic fields are equal in magnitude, but opposite in direction so that net magnetic field is zero and a compass needle if placed at the neutral point then it will rest in any direction.
