Electrons in projection television sets are acceler- ated through a total potential difference of 50,000 V. a. Calculate the speed of the electrons using the relativistic form of kinetic energy assuming the electrons start from rest.
b. Calculate the speed of the electrons using the classical form of kinetic energy.
c. Is the difference in speed signiï¬cant in the design of this set in your opinion?
