A metal rod mvoess 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 it velocity. Select the correct statement 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 electric potential is highest at the center of the rod and decreases towards its ends
D. The electric potential is lowest at the center of the rod and increases towards its ends

Answer

2

Explanation

According to Faraday.s law, an induced emf is set up on the rod whose magnitude is Blv. Thus, an electric field is generated in the rod. The electric potential varies uniformly along the rod
