Homework Help: Within what time interval can we create and destroy an electron-positron pair without

  1. Nov 15, 2009 #1
    The rest energy of an electron is 0.511 MeV = 8.2 x10-14 J. A positron is an electron with positive charge and the same rest energy. Within what time interval can we create and destroy an electron-positron pair without worrying about the conservation of energy? h = 6.626 × 10-34 J s.
