A Van de Graaff accelerator utilizes a 50.0 MV potential difference to accelerate charged particles such as protons. The kinetic energy provided by such a large potential difference is sufficiently great that relativistic effects need to be taken into account when finding the velocity of accelerated particles.
What is the velocity of a proton accelerated by such a potential?
What is the velocity of an electron accelerated by such a potential?
A -meson has a rest mass of 135 MeV. The proper lifetime of the -meson is s and an observer in a laboratory measures its lifetime as s. What is the kinetic energy of the -meson as measured by the observer?
