With respect to photoelectric experiment, match the entries of Column I with the enetires of Column II.

Answer

`(A) rarr (P,R); (B) rarr (Q,S); (C) rarr (S); rarr (D) rarr (P,R)`

Explanation

From `eV_(0) = hv- phi` and `K_("max") - hv - phi `. If v increase keeping `phi` constant constant, the `V_(0)` and `K_(max)` both incease.
If `phi` decrease keeping `v` constant, then `V_(0)` and `K_(max)` increase.
If `I` incrases more photoelectrons would be librated, hence saturation photocurrent increases.
If separation between cathode and anode is incrased, then there is no effect on `v_(0), K_(max)` or current.
