Question

Consider a uniform electric field in the z – direction. The potential is a constant

• A. For any x for a given z
• B. For any y for a given z
• C. On the x-y plane for a given z
• D. All of these

Answer 1

Answer: (D)

All of these

Answer 2

: As the electric field in the z – direction is uniform, equipotential surfaces are in xy plane. Hence the potential for given z is constant on x –y plane, for any x in this plane and for any Y in this plane. So all are correct.
