A) N and 2T
B) 2N and T
C) 2N and 2T
D) N and T
Correct Answer: B
Solution :
(i) Kinetic energy of photoelectrons depends on the frequency of incident radiations and is independent of the intensity of illumination. (ii) Number of photoelectrons depends upon the intensity. So, the number of emitted electrons and their maximum kinetic energy are 2N and T respectively.
