If the de Broglie wavelength of the electron in $n^{t h}$ Bohr orbit in a hydrogenic atom is equal to $1.5 π a_{0}$ $(a_{0}$ is Bohr radius $)$ , then the value of $\frac{n}{z}$ is:

Options:

Answer:

Solution:

$2 π r = n λ$

$2 π a_{0} \frac{n^{2}}{Z} = n λ$

$2 π a_{0} \frac{n^{2}}{Z} = n \times 1.5 π a_{0}$

$\frac{n}{Z} = \frac{1.5}{2} = 0.75$
