Problem

In a photoelectric-effect experiment, if

f

is the frequency of radiation incident on the metal surface and

I

is the intensity of the incident radiation, match the following columns.

Column I	Column II
(a) If $f$ is increased, keeping $I$ and work function constant	(p) Stopping potential increases
(b) If the distance between cathode and anode is increased	(q) Saturation current increases
(c) If $I$ is increased, keeping $f$ and work function constant	(r) Maximum kinetic energy of photoelectrons increases
(d) Work function is decreased, keeping $f$ and $I$ constant	(s) Stopping potential remains the same
