A photo cell is receiving light from a source placed at a distance of `1 m`. If the same source is to be placed at a distance of `2 m` , then the ejected electron

A photo cell is illuminated by a small bright source placed 1 m away. When the same source of light is placed 2 m away. The true statement about the electrons emitted by the photo cathode is

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 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

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 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

A photo cell is illuminated by a small bright source placed 1m away When the same source of light is placed 2m away, the electrons emitted by photo cathode

A photo cell is illuminated by a small bright source placed 1m away When the same source of light is placed 2m away, the electrons emitted by photo cathode
