Exercise 57

A uniform electric field of magnitude 375 N/C pointing in the positive x -direction acts on an electron, which is initially at rest. After the electron has moved 3.20 cm, what is (a) the work done by the field on the electron, (b) the change in potential energy associated with the electron, and (c) the velocity of the electron
