(a) Find the electric potential difference ΔVe required to stop
an electron
(called a “stopping potential”) moving with an initial speed of
2.85 x 10^7 m/s.
(b) Would a proton traveling at the same speed require a greater or
lesser
magnitude of electric potential difference? Explain.
(c) Find a symbolic expression for the ratio of the proton stopping
potential and
the electron stopping potential, ΔVp / ΔVe.
