If the distance of 100 Watt lamp is increased from a photocell, the saturation current i in the photo cell varies with distance d as

The saturation current I of a photocell varies with distance from the source ( d ) as :

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

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

A lamp is placed at a distance of 8 cm from a photocell and the microammeter records a current of 100 mu A . If the lamp is kept at a distance of 4 cm from the photocell, the photoelectric current recorded by the microammeter will be

When monochromatic source is kept at distance of 0.2 m from photocell,cutoff voltage obtained is 0.6 V and saturation current is 18 mA.Noe if source is kept at distance of 0.6 m…….
