An electron is a subatomic particle (m = 9.11x10^-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.81x10^5 m/s to a final velocity of +2.09x10^6 m/s while traveling a distance of 0.037 m. The electron's acceleration is due to two electric forces parallel to the x axis: F1 = +7.73x10^-17 N, and F2, which points in the -x direction. Find the magnitudes of the net force acting on the electron and the electric force F2.
