(a) Find the electric potential difference ΔVe required to stop an electron (called a "stopping potential") moving with an initial speed of 2.43x10^7 m/s.
(b) Would a proton traveling at the same speed require a greater or lesser magnitude of electric potential difference? Explain.
(c). Find an expression for the ratio of the proton stopping potential and the electron stopping potential.
