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$-II$?
$(1)$ Which of the following options has the correct combination considering List$-I$ and List$-II$?
$(1) (II), (R)(2) (I), (P)(3) (I), (T)(4) (II), (Q)$
($2$) Which of the following options has the correct combination considering List$-I$ and List$-II$?
$(1) (III), (S)(2) (IV), (Q)(3) (IV),(U)(4) (III), (P)$
Give the answer or quetion $(1)$ and $(2)$
| 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 | $(S)\propto n ^1$ |
| $(T)\propto n ^2$ | |
| $(U)\propto n ^{1 / 2}$ |
