83. (a) We assume the electron starts from rest. The classical formula for kinetic energy is Eq. 37-51, so if v = cthen this (for an electron) would be 21122(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 keV255 keV255.5 kV256 kV.
