When a monochromatic point source of light is at a distance

Last updated: 6/13/2023

When a monochromatic point source of light is at a distance of 0 2 m from a photoelectric cell the cut off voltage and saturation current are respectively 0 6 V and 18 0 mA If the same source 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 2 0 mA
