The electron gun in a color TV accelerates the electrons through about 25,000 Volts. Estimate the acceleration of such an electron due to the magnetic field of the earth. Hint: In Atlanta, the Earth's magnetic field has a magnitude of about 5.2 X 10-5 T.
The force on the electron is
F = e V B,
where V is the velocity and e is the electron charge. Get the velocity V from the energy.
(1/2) m V^2 = 25,000 V * e
Divide the force F by the electron mass m to get the acceleration.
