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 $n^{t h}$ orbit of the atom and List-II contains options showing how they depend on $n$ .

Question

List - I	List - II
(I) Radius of the $n^{t h}$ orbit	$(P)$ $\propto n^{- 2}$
(II) Angular momentum of the electron in the $n^{t h}$ orbit	$(Q)$ $\propto n^{- 1}$
(III) Kinetic energy of the electron in the $n^{t h}$ orbit	$(R)$ $\propto n^{0}$
(IV) Potential energy of the electron in the $n^{t h}$ orbit	$(S)$ $\propto n^{1}$
	$(T)$ $\propto n^{2}$
	$(U)$ $\propto n^{1 / 2}$

Which of the following options has the correct combination considering List-I and List-II?

Options:

Answer:

D

Solution:

According to Bohr’s atomic model:
Radius of orbit $\propto n^{2}$
Angular Momentum $\propto n$
Kinetic energy $\propto \frac{1}{n^{2}}$
Potential energy $\propto - \frac{1}{n^{2}}$
