In a region of constant potential, |
The electric field is non zero and uniform in the region There should be a charge inside the region The electric field changes linearly in the region The electric field is zero in the region. |
The electric field is zero in the region. |
The correct answer is Option (4) → The electric field is zero in the region. If the potential is constant, the gradient of the potential zero, which means the electric field is also zero. |
