A long horizontal metallic rod with length along the east-west direction is falling under gravity. The potential difference between its two ends will

STATEMENT - 1 : The magnetic flux through a closed surface is zero. STATEMENT - 2 : When a rod oriented along magnetic north and magnetic south direction falls under gravity. Potential difference developed across its ends is zero. STATEMENT - 3 : A resistance is connected to an ac source. If an inductor is included in the circuit in series. The average power dissipated in the resistance will decrease.

State Lenz's Law. A metallic rod held horizontally along east-west direction, is allowed to fall under gravity. Will there be an emf induced at its ends? Justify your answer.

Assertion: Length of the metal rod is aligned along northsouth direction and is released from rest under gravity. Potential difference is generated along the length of the rod. Reason: When a metal rod is moved perpendicular to its length and parallel to magnetic field then magnetic force on electrons generates electric field along the length of rod.
