In a TV tube an electric potential difference accelerates electrons from a rest position towards a screen. Just before reaching the screen, the electrons have a wavelength of 1.2×10-11m. Determine the kinetic energy of the electrons just before they reach the screen. Your final answer should have units of eV.
