Question

The wave function $(\Psi)$ of 2 s is given by $$ \Psi_{2 s}=\frac{1}{2 \sqrt{2 \pi}}\left(\frac{1}{a_0}\right)^{1 / 2}\left(2-\frac{r}{a_0}\right) e^{-r / 2 a_0} $$ At $r=r_0$, radial node is formed. Thus, $r_0$ in terms of $a_0$

Select the correct option:

$r_0=a_0$

$r_0=4 a_0$

$r_0=\frac{a_0}{2}$

$\mathrm{r}_0=2 \mathrm{a}_0$

✓ Correct! Well done.
