Question
A metal rod moves at a constant velocity in a direction perpendicular 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
Options
A.The entire rod is at the same electric potential
B.there is an electric field in the rod
C.the elctric potential is highest at the centre of the rod and decrease towards its end
D.the electric potential is lowest at the centre of the rod and increases towards its end
Solution
A motional emf, e = Blv is induced in the rod. Or we can say a potential difference is induced between the two ends of the rod AB, with A higher potetial and B at lower potential. Due to this potential difference, there is an electric field in rod.
