    Studying problem and help?

    A uniform electric field E exists between two conducting plates separated by a distance d. An electron is released from rest at the negative plate and is attracted to the positive plate.(a) Find its kinetic energy in terns of E, d and the electronic charge. (b) If E = 10^4 N/C find the velocity and kinetic energy at impact.

    It may be V=-Ed, in that case all of the signs in my post are wrong.
