57 When a monochromatic point source of light is at a distance r from a photoelectric cell the cut off voltage is V and the saturation current is I If the same source is placed at a distance 3r away from the photoelectric cell then a the saturation current will not change b the saturation current will change to I 9 c the stopping potential will not change d the stopping potential will increase to 3 V hotoelectric effect the
