Verified Answer
Assertion (A): Motional induction or flux cutting law gives the e.m.f....
- Assertion (A) is a correct statement since the motional induction or flux cutting law are given by
or, V = vBl volts - Motional emf equation depends only on the velocity of the conductor and not its position. Thus, reason (R) is not a correct statement,

Assertion (A): Motional induction or flux cutting law gives the e.m.f....
Explanation:
To explain why option 'C' is the correct answer, we need to understand the definitions of motional induction and the flux cutting law.
Motional Induction:
- Motional induction refers to the generation of an electromotive force (emf) in a conductor that is moving through a magnetic field.
- This phenomenon is described by Faraday's law of electromagnetic induction, which states that the emf induced in a conductor is directly proportional to the rate of change of magnetic flux through the conductor.
Flux Cutting Law:
- The flux cutting law states that when a conductor moves through a magnetic field, it cuts the magnetic field lines, which results in the generation of an emf in the conductor.
- The emf induced is proportional to the velocity of the conductor and the length of the conductor that is cutting the magnetic field lines.
Analysis of Assertion and Reason:
- The assertion (A) that motional induction or flux cutting law gives the emf induced in a moving conductor with respect to an observer in a magnetic field is true.
- However, the reason (R) that the motional emf equation depends on the velocity of the conductor and its position is false.
- The emf induced in a moving conductor is dependent on the velocity of the conductor and the rate of change of magnetic flux, not its position.
Therefore, option 'C' is the correct answer as the assertion is true (A) while the reason is false (R).
