Finalanswer asks for
plate so take Heatswer
Review bc0potential energy final position only KE
we kept units consistent throughout and the that units of Ncis the
units for electric field strength
Based on Esif we increase the distance from the electron to the
plate the electric field strength detreases This makes sense b
an electron further away from the plate would feel less affect of the field
