Two parallel conducting plates that are in deep space are brought to a potential difference of 3500 V, and a small pellet of mass 6.95 mg carrying a charge of 6.70 × 10-7 C accelerates from rest from the positive plate. With what speed will it reach the other plate?
I'm thinking conservation of energy.
The Attempt at a Solution
I know that Ki ends up being 0 so it just becomes Ui=Kf+Uf. I have no idea what the potential energy would be since I don't have a distance.?
