When a monochromatic point source of light is ata distance of 0.2m from a photocell, the cut-off voltage and saturation current ar0.6 v and 18mA respectively. If the same source is placed 0.6 maway from the photoelectric cell, then - the stopping potential will be 0.2 v
- the stopping potential is 0.6V
- the saturation potential will be 6mA
answer (b)
