Question

The curves (a),(b),(c) and (d) show the variation between the applied potential difference (V) and the photoelectric current (i), at two different intensities of light (I1 > I2). In which figure is the correct variation shown? (A)  (B)  (C)  (D)

I1>I2 (given) ⇒ i1>i2 (∵ i propto I) and stopping potential does not depend upon intensity. So its value will be same (V0).

Q. The curves $(a), (b), (c)$ and $(d)$ show the variation between the applied potential difference $(V)$ and the photoelectric current $(i)$ , at two different intensities of light $(I_{1} > I_{2})$ . In which figure is the correct variation shown?

$I_{1} > I_{2}$ (given)
$\Rightarrow i_{1} > i_{2} (∵ i \propto I)$
and stopping potential does not depend upon intensity. So its value will be same $(V_{0})$ .

Q. The curves (a),(b),(c) and (d) show the variation between the applied potential difference (V) and the photoelectric current (i), at two different intensities of light (I1​>I2​). In which figure is the correct variation shown?

I1​>I2​ (given) ⇒i1​>i2​(∵i∝I) and stopping potential does not depend upon intensity. So its value will be same (V0​).
