(a) Find the electric potential difference AV required to stop an electron (called a "stopping potential") moving with an initial speed of 1.86 x 10 m/s. you submitted has the wrong sign. kv (b) Would a proton traveling at the same speed require a greater or lesser magnitude of electric potential difference? greater Olesser O equal Explain. a proton traveling at the same speed as the electron would require a greater magnitude of electric potential difference. This is because the proton has a greater mass than the electron and requiles more energy to stop it. (c) Find a symbolic expression for the ratio of the proton stopping potential and the electron stopping potential, Av Jav (Use the following as necessary: m, for the man proton and m, for the mass of electron.)
