The picture tube in an old black-and-white television utilizes magnetic deflection coils rather than electric deflection plates. Presume an electron beam is accelerated during a 52.8-kV potential difference and then through a region of uniform magnetic field 1.00 cm wide. The screen is located 10.9 cm from the center of the coils and is 45.2 cm wide. When the field is turned off, the electron beam hits the center of the screen. Ignoring relativistic corrections, what field magnitude is necessary to deflect the beam to the side of the screen?
