  • a)
    Some of the electrons emitted have a kinetic energy of 0.5 eV.
  • b)
    Stopping potential is 2 V.
  • c)
    Photoelectric emission will stop after some time even if the incident radiation is not stopped.
  • d)
    Photoelectric emission will continue as along as there is incident radiation.
Correct answer is option 'A,C'. Can you explain this answer?

KEmax = hυ − W
= hc/λ - W
= (12400/4000 - 2)eV
= 1.1 eV
Emitted electron can have kinetic energy from 0 to 1.1 eV.
After sometime the metal plate gets '+'charge and the electrong cant overcome the potential so photoelectric effect stops
