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 +5.18 x 105 m/s to a nal velocity of 2.06 x 106' m/s while traveling a distance of 0.0381 m. The > > electron's acceleration is due to two electric forces parallel to the x axis: F1 = 7.00 x 10'17 N, and F2, which points in the -x direction. _) Find the magnitudes of (a) the net force acting on the electron and (b) the electric force F2
