In a television set, electrons are accelerated from rest through a potential difference of 19 kV. The electrons then pass through a 0.28 Tesla magnetic field that deflects them to the appropriate spot on the screen. What is the magnitude of the maximum magnetic force that an electron can experience?

Solution Summary

Problem is solved considering the force acting on an electron moving through a magnetic field.

Solution Preview

When an electron is accelerated from rest through a potential difference of V volts, it acquires kinetic energy equal to eV Joule where e is the charge on an electron.

Thus, 1/2 mv^2 = eV where m = ...
