Question

A metal rod moves at a constant velocity in a direction perpendiuclar to its length A constant uniform magnetic field exists in space in a direction perpendicular to the rod as well as its velocity. Select the correct statement (s) from the following. (A) The entire rod is at the same electric potential (B) There is an electric field in the rod (C) The electric potential is highest at the centre of the rod and decrease towards its ends (D) The electric potential is lowest at the centre of the rod and increases towards its ends

A motional emf, e = Bl ν is induced in the rod. Or we can say a potential difference is induced between the tow ends of the rod AB,with A at higher potential and B at lower potential . Due to this potential difference, there is an electric field in the rod .

The entire rod is at the same electric potential

There is an electric field in the rod

The electric potential is highest at the centre of the rod and decrease towards its ends

The electric potential is lowest at the centre of the rod and increases towards its ends

A motional emf, $e = Bl ν$ is induced in the rod. Or we can say a potential difference is induced between the tow ends of the rod AB,with A at higher potential and B at lower potential . Due to this potential difference, there is an electric field in the rod .
