REVIEWING OLD TEST and.. dont understand why you use the full distance.

1. The problem statement, all variables and given/known data
pretty much theres a home made capacitor made by two pie pans 3.5 cm apart. V is given Q is given, the question asks:
calculate the electric field halfway between the plates

2. Relevant equations
dV=Ed


3. The attempt at a solution

you just simply plug in, but why is distance the full 3.5 cm and not half of that, as youre finding the field at a distance that is halfway between the plates? am i answering my own question and the E field is constant?

Yes, the electric field is uniform between the plates so it would be the same.
