Two charged plates are 2mm apart. An electron escapes from the negatively charged plate and reaches the positively charged plates in 1.2x10^-8 seconds. Find the electric field between the plates.
eV= + or - 1.6x10^-19 C
The Attempt at a Solution[/B]
The only way I could think of doing this is below but I'm not confident in my answer whatsoever.
(unsure how to find velocity, too, given the numbers in the problem)
V= (1.60x10^-19C )x(1.2x10^-8s)
E= 3.84x10^-30 N/C
