An electron is a subatomic particle (m = 9.11 x 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +5.71 x 105 m/s to a final velocity of 2.89 x 106 m/s while traveling a distance of 0.0834 m. The electron's acceleration is due to two electric forces parallel to the x axis: = 9.22 x 10-17 N, and , which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force .
