A photon of 6eV is incident on a metal surface and the emitted electron is stopped by a retarding potential of -5eV .What will be the work function of the metal??

Question

Abhishek Kumar · Answer

As the electron is stopped by -5eV, KE = 5eV So, Work function of the metal = 6eV &ndash; 5eV = 1eV

Anish Bhusal · Answer

By einstein’s photoelectric eqn, Work function= incident energy – retarding potential So, workfunction= 1eV
