JEE Main 2021 Physics question

The radiation corresponding to 3 2 transition of a hydrogen atom falls on a gold surface to generate photoelectrons. These electrons are passed through a magnetic field of T. Assume that the radius of the largest circular path followed by these electrons is 7 mm, the work function of the metal is : (Mass of electron = kg)

• (A)1.36 eV
• (B)1.88 eV
• (C)0.16 ev
• (D)0.82 eVCorrect
