An electron in the beam of a typical television picture tube

Reference no: EM13652287

An electron in the beam of a typical television picture tube is accelerated through a potential difference of 20,000 V before it strikes the face of the tube. What is the speed of the electron? what is the eneregy of the electron in joules? what is the energy of the electron in electron volts?
