Question
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.
Options
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true and Reason is not the correct explanation of Assertion
Assertion is true but Reason is false
Assertion is False but Reason is true
