MCQ
Answer the following by appropriately matching the lists based on the information given in the paragraph Consider the Bohr's model of a one-electron atom where the electron moves around the nucleus. In the following $List-I$ contains some quantities for the $n^{t /}$ orbit of the atom and $List-II$ contains options showing how they depend on $n$.
Which of the following options has the correct combination considering $List-I$ and $List-II$?
| $List-I$ | $List-II$ |
| $(I)$ Radius of the $n^{\text {th }}$ orbit | $(P)$ $\propto n ^{-2}$ |
| $(II)$ Angular momentum of the electron in the $n^{\text {th }}$ orbit | $(Q)$ $\propto n ^{-1}$ |
| $(III)$ Kinetic energy of the electron in the $n^{\text {th }}$ orbit | $(R)$ $\propto n ^0$ |
| $(IV)$ Potential energy of the electron in the $n^{\text {th }}$ orbit | $(S)$ $\propto n ^1$ |
| $(T)$ $\propto n ^2$ | |
| $(U)$ $\propto n ^{1 / 2}$ |
