(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have attached the question.

2. Relevant equations

a)Potential Energy the electron gains = Kinetic energy it looses

1eV = 1.6 * 10^-19

Total P.E gained by the electron = 100 * 1.6 * 10^-19 = 1.6*10^-17

Therefore the kinetic energy it must possess to reach the plate RS is 1.6 *10^-17 J.

I am wrong but I am not sure where I am incorrect. Any help would be appreciated. =)

b) I am not very sure on how to go about doing this part of the question as I would need the initial velocity, or the acceleration or time taken for it to reach B to find the velocity of electrons that emerge from B?

Thank you.
