Question:

In the photoelectric effect, the slope of the stopping potential $V_0$ versus frequency $\nu$ graph equals / प्रकाश-विद्युत प्रभाव में निरोधी विभव $V_0$ बनाम आवृत्ति $\nu$ ग्राफ की प्रवणता बराबर है

1.
$h/e$ / $h/e$
2.
$e/h$ / $e/h$
3.
$h\nu/e$ / $h\nu/e$
4.
$e\nu/h$ / $e\nu/h$

Correct Answer: $h/e$ / $h/e$

From $eV_0 = h\nu - \phi$, $V_0 = (h/e)\nu - \phi/e$, so the slope is $h/e = 4.14 \times 10^{-15}$ V·s. / $eV_0 = h\nu - \phi$ से, $V_0 = (h/e)\nu - \phi/e$, अतः प्रवणता $h/e = 4.14 \times 10^{-15}$ वोल्ट-सेकंड है।
