The work function of a certain metal is ...

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:

A

`V+(100etalambdaPet)/(4piepsilonRhC)`

B

`V-(etalambdaPet)/(400piepsilonRhC)`

C

V

D

`(lambdaPet)/(4piepsilonRhC)`
