1. The problem statement, all variables and given/known data An electron is released from rest from the negative plate of a parallel-plate apparatus, what is the electrons speed one third of the way between the plates. It also asks for the speed at which electron will hit the positive plate if a 450 V potential difference is applied. 3. The attempt at a solution a) Eel = V x q Eel = ( 450 V ) x (1.6 x 10^-19C) Eel = 7.2 x 10^17 J Eel = 1/2mv^2 V = √((2 x (7.2 x 10^17 J))/9.1 x 10^31Kg) V = 1.26 x10^7 m/s b) i don't know how to do this?
