Q 11) An electron beam moves toward a cathode ray tube screen, which is 20 cm away from the negative electrode. The electrons are accelerated by a potential difference of 18 kV. Estimate the maximum displacement of the electron beam caused by Earth's magnetic field. The average magnetic field at the surface of Earth is roughly BE = 45×10^−6T. Express your answer with the appropriate units.
