When a monochromatic point source of light is at a distance of 0.2 m from a photoelectric cell, the cut-off voltage and the saturation current are respectively 0.6 V and 18.0 mA. If the
same source is placed 0.6 m away from the photoelectric cell, then

the stopping potential will be 0.2 V
2
the stopping potential will be 0.6 V
3
the saturation current will be 6.0 mA
