Question

Assertion (A): In the presence of magnetic field, the needle of a compass aligns itself in the direction of magnetic field.

Reason (R): The needle of a compass always points in the north-south direction in the absence of any other magnetic field.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

Explanation:

A compass needle, being a small magnet, aligns itself along the direction of the magnetic field in which it is placed. In the absence of any other magnetic field, it points north-south because of Earth's magnetic field. Thus, both statements are true, but Reason does not explain the Assertion.
