Dual Nature Of Light Question 405
Question: The maximum kinetic energy of photoelectrons emitted from a surface when photons of energy 6 eV fall on it is 4 eV. The stopping potential, in volt, is
Options:
A) 2
B) 4
C) 6
D) 10
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Stopping potential is the negative potential applied to stop the electrons having maximum kinetic energy. Therefore, stopping potential will be 4 volt.
