Question

When a siurce of light is at a distance of 50cm from a photoelectric effect cell the cut off voltage is found to be V0.if the same source is placed at a distance of 1m from cell then the cut off voltage will be

Answer 1

Explanation:

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 Vo If the same source is placed at a distance of 1 m from the cell, then the cut-off voltage will be 4
