Plz I need help (Relativity Question)

  1. Nov 16, 2007 #1
    1. The problem statement, all variables and given/known data

    Electrons are accelerated up to a kinetic energy of 10^9 eV. Find:-

    (a) the ratio of their mass to the rest mass,
    (b) the ratio of their velocity to the velocity of light,
    (c) the ratio of their total energy to their rest mass energy.

    1 eV=1.6x10^-19 Joule, c=3x10^8 msec^-1
