An electron moving with speed of $5.0\times 10^8$cm/sec is shot parallel to an electric field strength of $1.0\times 10^3 $nt/coul arranged so as to retard its motion.
- How far will the electron travel in the field before coming (momentarily) to rest ?
- how much time will elapse?
- If the electric field ends abruptly after $0.8$ cm, what fraction of its initial energy will the electron loose in traversing the field?
