Question

The deflection of the electron beam in an old-fashioned tube TV set is accomplished by magnetic forces. Each electron is accelerated through a potential difference of V=45000V. Magnetic field B=0.005 T is required to produce a deflection of y1=0.015m if the magnetic field region is x1=0.065m long. The charge to mass ratio of the electron is 175824175824.176C/kg.

If there is a x2=0.14m gap between the end of the magnetic field region and the end of the tube, how far from the center of the screen does the beam strike?
ynet = y1 + y2 = _______ m

Explanation / Answer

R = (m/eB)*v(2eVacc/m)
