Question

Consider a uniform electric field in the
^
z
direction. The potential is a constant
(a) in all space.
(b) for any x for a given z.
(c) for any y for a given z.
(d) on the x-y plane for a given z.
Solution

Answer 1

Explanation:

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.

Answer 2

Answer:

d- on the x-y plane for a given z .

Explanation:

because equipotential surface are in xy plane
