Question

Aicharya · Accepted Answer

Velocity of electron in the $\mathrm{n}^{\mathrm{th}}$ orbit $\mathrm{y}_{\mathrm{n}}=\frac{\mathrm{Ze}^2}{2 \varepsilon_0 \mathrm{nh}}$ $\begin{aligned} & \Rightarrow \mathrm{v}_{\mathrm{n}} \propto \frac{1}{\mathrm{n}} \ & \quad 	ext { given } \mathrm{n}_1=1 	ext {, and } \mathrm{n}_2=2, \ & 	herefore \quad \frac{\mathrm{v}_1}{\mathrm{v}_2}=\frac{\mathrm{n}_2}{\mathrm{n}_1}=\frac{2}{1} \end{aligned}$ *
