A beam of light of wavelength λ is incident on a metal having work function ϕ and placed in a magnetic field B. The most energetic electrons emitted perpendicular to the field are bent in circular arcs of radius R. Then 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.
