Vedclass · Answer

(A) $1$. In the photoelectric effect, when the anode potential is negative, the photoelectric current decreases as the retarding potential increases.$2$. At the stopping potential $(V_0)$, the most energetic photoelectrons are repelled, and the photoelectric current becomes zero.$3$. As the anode potential increases from $V_0$ towards positive values, the photoelectric current increases and eventually reaches a saturation value due to the collection of all emitted photoelectrons.$4$. Graph-$I$ correctly represents this characteristic curve, showing the current starting from zero at $V_0$ and increasing to a saturation level.

The variation of photoelectric current with anode potential is shown below. Choose the correct option ($V_0$ = stopping potential).
