QuestionDetails: A uniform electric field of magnitude 375 N/C pointing in thepositive x direction acts on an electron, which is initially atrest. After the electronhas moved 3.20 cm, what is (a) thework done by the field electron, (b) the charge in potential energyassociated with the electron, and (c) the velocity of theelectron?

Explanation / Answer

A uniform electric field E = 375 N/C Charge of electron q = 1.6 * 10 -19 C Mass of electron m = 9.1 * 10 -31 kg (a). the work done by the field electron W = F S                                                                 = E q S where S = distance = 3.2 cm = 0.032 m Substitue values wgeet answer (b). the charge in potential energy associated with theelectron = W (c).  the velocity of the electron v = [ 2W /m ]     Since work done = change in K.E                                                                                                    W = ( 1/ 2) m v 2 Substitue values weget answers Substitue values weget answers
