WebApr 10, 2024 · Stopping potential, or cut-off potential, is defined as the required potential for stopping the removal of an electron from a metal surface when the incident light energy … WebPhotoelectric cut-off voltage, V 0 = 1.5 V. The maximum kinetic energy of the emitted photoelectrons is given as: K e = eV o Where, e = Charge on an electron = 1.6 × 10 −19 C. ∴ K e = 1.6 x 10-19 x 1.5 = 2.4 x 10-19 J. Therefore, the maximum kinetic energy of the photoelectrons emitted in the given experiment is 2.4 × 10 −19 J.
