The work function of a certain metal is `(hC)/lambda_(0)`. When a monochromatic light of wavelength `lambda lt lambda_(0)` is incident such that the plate gains a total power `P`. If the efficiency of photoelectric emission is `eta%` and all the emitted photoelectrons are captured by a hollow conducting sphere of radius `R` already charged to potential `V`, then neglecting any interaction of potential of the sphere at time `t` is:

Options

A. `V+(100eta lambda Pet)/(4piepsilon_(0)RhC)`
B. `V=(etalambdaPet)/(400pi epsilon_(0)RhC)`
C. `V`
D. `(lambdaPet)/(4 pi epsilon_(0)RhC)`

Answer

B
