I need help with part B I don't understand it

Physicists often use a different unit of energy, the
electron volt, when dealing with energies at the
atomic level. One electron volt, abbreviated eV, is
defined as the amount of kinetic energy gained by
an electron upon accelerating through a 1.0 V
potential difference.
