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?
