Physics

An electron with a speed of 7.61 Ã— 10⁸ cm/s in thepositive direction of an x axis enters an electric fieldof magnitude 1.14 Ã— 10³ N/C, traveling along a fieldline in the direction that retards its motion. (a)How far will the electron travel in the field before stoppingmomentarily, and (b) how much time will haveelapsed? (c) If the region containing the electricfield is 7.36 mm long (too short for the electron to stop withinit), what fraction of the electronâ€™s initial kinetic energy will belost in that region?
