JEE Main 2021 Physics question

An electron and proton are separated by a large distance. The electron starts approaching the proton with energy 3 eV. The proton captures the electrons and forms a hydrogen atom in second excited state. The resulting photon is incident on a photosensitive metal of threshold wavelength 4000 Å. What is the maximum kinetic energy of the emitted photoelectron?

• (A)7.61 eV
• (B)1.41 eVCorrect
• (C)3.3 eV
• (D)No photoelectron would be emitted
