83. (a) We assume the electron starts from rest. The classical formula for kinetic energy is Eq. 37-51, so if v = c then this (for an electron) would be 2 11 22 (511 ke V) mc == 255.5 ke V (using Table 37-3). Setting this equal to the potential energy loss (which is responsible for its acceleration), we find (using Eq. 25-7) 255.5 keV 255 keV 255.5 kV 256 kV.
