a) Consider a particle of mass m and charge e, accelerated from rest through an electric potential difference V. Assuming non-relativistic mechanics for the particle, what is the particle's final kinetic energy? Its final momentum? Its final speed? b) Investigate what happens when the accelerated charge is subjected to a magnetic field perpendicular to the charge's trajectory. c) Ponder about the scientific question of your research with this experiment. Your proposed research MUST be with the apparatus described below (figure 1), with only minor modifications. Consult the lab instructor in case of questions about the apparatus. An example of the scientific question is: A flow of charged particles with constant speed forms a current. If that current is subjected to a perpendicular magnetic field, it should experience a force perpendicular to both the current and the magnetic field. If the magnitude of the magnetic field is known, could one measure the bending of the current to estimate the magnitude of the flowing charges? d) Based on this investigation, write an Introduction to your lab report. Clearly state the hypothesis of your experiment. e) Study the experimental set-up and the operation manual below, and write the Experimental section of your Lab Report, describing, in detail, how the experiment works and the purpose of each component in the set-up. f) Pay close attention to safety procedures. a) Consider a particle of mass m and charge e, accelerated from rest through an electric potential difference V.
