1. An electron travels through an electric field. The kinetic energy of the electron changes from 4.00 x 10-18 J to 3.95 x 10-18 J. Determine: a) the change in kinetic energy of the electron, b) the fall in electrical potential (voltage). c) its total energy (EPE + EC), at any point in its trajectory. (Remember the energy is conserved.) (EPEinitial = 0.00 J)
