An electron is observed traveling at a speed of 1.89 107 m/s parallel to an electric field of magnitude 10,660 N/C. How far will the electron travel before coming to a stop? (The mass of electron is 9.109 10-31 kg, and the charge on the electron is 1.602 10-19 C. The electron is moving in the direction opposite to the electric field.)
