A uniform electric field of magnitude 430 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 2.80 cm.
(a) What is the work done by the field on the electron?
(b) What is the change in potential energy associated with the electron? .
(c) What is the velocity of the electron?
