Question
The work function of a certain metal is 
. When a monochromatic light of wavelength λ < λ0 is incident such that the plate gains a total power P. If the efficiency of photoelectric emission is h% and all the emitted photoelectrons are captured by a hollow conducting sphere of radius R already charged to potential V, then neglecting any interaction between plate and the sphere, expression of potential of the sphere at time t is :
