Is it 2 dimensional or 3 dimensional?
Space is 3 dimensional, so any field is 3 dimensional.
Did you have a specific electric field in mind?
EDIT: just occurred to me …
if a field was 2 dimensional, it would fall off as 1/r instead of 1/r2, since it would spread out over a circle (~ r) instead of a sphere (~ r2)
thanks, I was just going over physics 2 material which I'll take next semester.
