An electron with a speed of 5.00E8 cm/s enters an electric eld of magnitude 1.00E3 N/C, traveling along a field line in the direction that retards its motion. (a) How far will the electron travel in the eld before stopping momentarily? (b) How much time will have elapsed? (c) If the region containing the electric eld 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?
