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)

An electron with kinetic energy 228 eV is moving in a horizontal direction. The electron moves into a region where there is a uniform vertical electric field which has magnitude 3990 N/C. Find the smallest magnitude of a magnetic field that will cause the electron to continue to move horizontally. (1eV=1.6^10^(-19)J;mass of the electron=9.11*10^(-31)kg)
