The potential is constant throughout a given region of space.Is electrical field zero or non-zero?
Have you looked up the relationship between Potential and Field? What does it tell you? What does Potential Difference mean?
Would you need to do work (or get it out) to move a charge in the direction of a field? This is all good old book work and it would be better for you to look it up for yourself.
Tell us what you think, and why, and someone will be glad to correct you if necessary.
I think that it would be zero because E=delta V / delta d. As V is constant therefore delta V =0
You should have more confidence. Did it seem too good to be true? :)
There are not many occasions where the Maths gives you the wrong answer. (It's probably more reliable than some old loony, answering you on PF.)
