These consist of two statements – Assertion (A) and Reason (R). Answer these questions selecting the appropriate option given below:
Assertion: On freely suspending a current – carrying solenoid, it comes to rest in Geographical N-S direction.
Reason: One end of current carrying straight solenoid behaves as a North pole and the other end as a South pole, just like a bar magnet.
पर्याय
