When you shine a certain source of em radiation on a sheet of gold. (Work function W1=5.1 eV) the stopping voltage is required to bring all ejected electrons to a halt. Is V1=3.5 V. If you were to use this same source of EM radiation on a sheet of potassium. (Work function W2=2.3 eV) what would the max speed of ejected electrons?
