about 12,000 V. Estimate the a? The electron gun in a TV (Traditional CRT) accelerates the electrons through about 12,000 V. Estimate the acceleration that electron would feel due to the magnetic field of the earth. If this acceleration went uncorrected, estimate how far it would shift the image on your TV screen?
 
Ke=(1/2)m(v^2)

The mass of an electron: 9,1*10^31
The kinetic energy: Ke=12 keV

So:
1 452 546 m/s
