An electron and a proton are each accelerated starting from rest through a potential difference of 10 / ε million volts.As an example, if ε=1 each particle would have a kinetic energy of 10 MeV.
a) Find the momentum (in MeV/c) of each and find the % error when the classical formula is used.
b) Find the kinetic energy (in MeV) of each and find the % error when the classical formula is used.
