Photoelectric current increases
Photoelectric current decreases
Kinetic energy of emitted photoelectrons increases
Work function of metal A is equal to the ionization energy of hydrogen atom in the first excited state. Work function of metal B is equal to the ionization energy of He+ ion in the second orbit. Photons of same energy E are incident on both A and B. Maximum kinetic energy of photoelectrons emitted from A is twice that of photoelectron emitted from B. The difference in maximum kinetic energy of photoelectrons from A and from B.
