When radiation is incident on a photoelectron emitter, the stopping potential is found to be 9V. If e/m for the electron is 1.8×10^11Ckg^−1, the maximum velocity of the ejected electrons is the maximum velocity of the ejected electrons is the stopping potential is found to be 9V. If e/m for the electron is 1.8×10^11Ckg^−1 When [...]
