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 :
- 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.
Answer
(B) There is an electric field in the rod
