An electron gun is a device that sets up an electric field between two plates. The electrons start on the negative plate and thenare accelerated toward the positive plate and out a small hole in its middle if an electron in the gun feels the effect of 5.00x10^5 N/C. What is its acceleration?

E=5 x 10^5 N/C

m =9.1 x 10^-31 kg
e= 1.6 x 10^-19 C
ma=eE
a= eE/m
