When a point source of light is at a distance of 50 cm from a photoelectric cell , the cut-off voltage is found to be ` V_(0)` . If the same source is placed at a distance of 1 m from the cell , then the cut-off voltage will be

When a point source of light is at a distance of one metre from a photo cell , the cut off voltage is found to be V . If the same source is placed at 2 m distance from photo cell , the cut off voltage will be

When a point source of light is at a distnace of 1 m from a photo cell, the cut off voltage is is found to be V. if the same source is placed at 3m distance from photo cell, the cut of voltage will be

A source of light is placed at a distance of 1 m from a photo cell and the cut off potential is found to be 5 V. If the source is kept at 1.5 m from the cell, then the cut off potential will be

A source of light is placed at a distance of 1 m from a photo cell and the cut off potential is V_0 . If the source of light is placed at a distance of 50 cm, the cut off potential will be :

when a monochromatic point source of light is at a distance 0.2 m from a photoelectric cell, the saturation current and cut-off voltage are 12.0 mA and 0.5 V. If the same source is placed 0.4 m away from the photoelectric cell, then the saturation current and the stopping potential respectively are
