Vedclass · Answer

(C) According to Einstein's photoelectric equation,the maximum kinetic energy of emitted photoelectrons is given by $KE_{\max} = h
u - \phi_0$,where $h$ is Planck's constant,$
u$ is the frequency of incident light,and $\phi_0$ is the work function of the material.Since the stopping potential $V_0$ is defined as the potential required to stop the most energetic electrons,we have $eV_0 = KE_{\max}$.Therefore,$V_0 = \frac{KE_{\max}}{e} = \frac{h
u - \phi_0}{e}$.$1$. $V_0$ depends on the frequency $
u$ of incident light (Option $B$ is true).$2$. $V_0$ depends on the work function $\phi_0$,which depends on the nature of the emitter material (Option $A$ is true).$3$. $V_0$ is $1/e$ times the maximum kinetic energy (Option $D$ is true).$4$. $V_0$ does not depend on the intensity of the incident light,as intensity only affects the number of photoelectrons emitted,not their individual kinetic energy (Option $C$ is false).
