प्रश्न

Assertion (A): A current carrying straight conductor experiences a force when placed perpendicular to the direction of magnetic field.

Reason (R): The net charge on a current carrying conductor is always zero.

पर्याय

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

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

  • (A) is true, but (R) is false.

  • (A) is false, but (R) is true.

MCQ

उत्तर

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

Explanation:

Both statements are true but logic does not support either. The conductor experiences force as a result of the magnetic field's interaction with the external magnetic field.
