Problem
The wavelength associated with an electron beam used in an experiment is measured to be 0.15nm.
(i) Determine the linear momentum of each electron in the beam.
(ii) Hence calculate the speed of the electrons, assuming non-relativistic motion.
(iii) Estimate the kinetic energy of each electron in electron-volts.
