SUMMARY
The kinetic energy of an electron ejected from a hydrogen atom due to the photoelectric effect can be calculated using the equation E = W + KE, where E is the energy of the incoming photon (15.2 eV), W is the work function (binding energy of the electron), and KE is the kinetic energy of the ejected electron. In this scenario, the binding energy of the electron in the ground state of hydrogen is approximately 13.6 eV. Therefore, the kinetic energy of the ejected electron is calculated as KE = E - W = 15.2 eV - 13.6 eV = 1.6 eV. This demonstrates the conservation of energy principle in the photoelectric effect.
