MCQ
What is the stopping potential when the metal with work function $0.6 \mathrm{eV}$ is illuminated with the light of $2 \mathrm{eV}$
  • A
    $2.6 \mathrm{~V}$
  • B
    $3.6 \mathrm{~V}$
  • C
    $0.8 \mathrm{~V}$
  • $1.4 \mathrm{~V}$

Answer

Correct option: D.
$1.4 \mathrm{~V}$
$V_0=\frac{\left(E-W_0\right)}{e}=\frac{(2 e V-0.6 \mathrm{eV})}{e}=1.4 \mathrm{~V}$
