Explanation:
Given that,
Initial speed of the electron,
Distance, s = 5 cm = 0.05 cm
Acceleration of the electron,
(a) Let v is the electron's velocity when it emerges from this region. It can be calculated as :
v = 871779.788 m/s
or
(b) Let t is the time for which the electron take to cross the region. It can be calculated as:
Hence, this is the required solution.
