A uniform electric field of magnitude 380 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 2.60 cm.
(a) What is the work done by the field on the electron? J
(b) What is the change in potential energy associated with the electron? J
(c) What is the velocity of the electron? magnitude m/s direction +x,-x,+y-y
