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

A

be zero

B

be constant

C

increase with time

D

decrease with time

Text Solution

Verified by Experts

The correct Answer is:
C
Induced emf, e = Bvl
`therefore" "e prop v`
Also, v = 0 + gt
`therefore" "e prop "gt"`
So, potential difference between its two ends will increase with time.

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.
