Consider an electron ejected from a metal in a photoelectric effect experiment with a kinetic energy of 6.4e−196.4𝑒−19 J. For this electron, what stopping potential (in Volts) is required to prevent it from being detected as part of the current in the experiment? (Please give your answer to two decimal places
