1 When a point source of monochromatic light is at a distance of 0 2 m from a photoelectric cell the cut off voltage and the saturation current are 0 6 volt and 18 mA respectively If the same source is placed 0 6 m away from the photoelectric cell then 1 The stopping potential will be 0 2 V 2 The stopping potential will be 0 6 V 3 The saturation current will be 6 mA 4 The saturation current will be 18 mA
