Question
Draw three equipotential surfaces corresponding to the field whose magnitude increases uniformly, but remains constant along the z-direction. How are these surfaces different from those that lie along the z- direction of a constant electric field?

Answer

Image
$E _2=\frac{ V _3- V _2}{d_2}$
$E _1=\frac{ V _2- V _1}{d_1}$
If E is uniform then $d_1=d_2$|
For a uniform field, the potential on every plane will be the same
