An electron (m = 9.11 x 10^-31 kg) is accelerating in the uniform field E (E = 1.85 x 10^4 N/C) between 2 parallel charged plates. The separation of the plates is 1.2 cm (.012 m). The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate. a.What speed does it leave the hole? b.Show that gravitational force can be ignored. a. I know that E = F/q, where F = ma. Given: E = 1.85 x 10^4 N/C, r (or x) = .012 m, m = 9.11 x 10^-31 kg, but what is q? Using mathematical definitions, I can solve for v. E = ma/q, where a = Eq/m v = x/t a = v/t a*t = x/t t = sqrt(x/a) Then I can plug in x and t values for v = x/t. Correct??? b. I have no idea how to carry out this proof. Need help! Thanks.
