In a historical experiment to determine Planck's constant, a metal surface was irradiated with light of different wavelengths. The emitted photoelectron energies were measured by applying a stopping potential. The relevant data for the wavelength $(\lambda)$ of incident light and the corresponding stopping potential $\left(V_0\right)$ are given below :

$\lambda(\mu \mathrm{m})$ $V_0$ (Volt)
$0.3$ $2.0$
$0.4$ $1.0$
$0.5$ $0.4$

Given that $c=3 \times 10^8 \mathrm{~m} \mathrm{~s}^{-1}$ and $e=1.6 \times 10^{-19} \mathrm{C}$, Planck's constant (in units of $\mathrm{J}$ s) found from such an experiment is
