An electron with a speed of 5.00 x 108cm/s enters an electric field of magnitude 1.00 x 103N/C, traveling along a field line in the direction that retards its motion.
(a) How far will the electron travel in the field before stopping momentarily, and
(b) How much time will have elapsed?
(c) If the region containing the electric field is 8.00 mm long (too short for the electron to stop within it), what fraction of the electron's initial kinetic energy will be lost in that region?
