Question

TuteeHUB · Accepted Answer

$${{K}_{n}}\propto \frac{1}{n},{{r}_{n}}\propto n$$

TuteeHUB · Answer

$${{K}_{n}}$$ independent of n, $${{r}_{n}}\propto n$$

TuteeHUB · Answer

$${{K}_{n}}\propto \frac{1}{n},{{r}_{n}}\propto {{n}^{2}}$$

TuteeHUB · Answer

$${{K}_{n}}\propto \frac{1}{{{n}^{2}}},{{r}_{n}}\propto {{n}^{2}}$$

1.	Suppose an electron is attracted towards the k origin by a force \[\frac{k}{r}\] where A: is a constant and r is the distance of the electron from the origin. By applying Bohr model to this system, the radius of the nth orbital of the electron is found to be \['{{r}_{n}}'\] and the kinetic energy of the electron to be\['{{K}_{n}}'\]. Then winch of the following is true
A.	\[{{K}_{n}}\] independent of n, \[{{r}_{n}}\propto n\]
B.	\[{{K}_{n}}\propto \frac{1}{n},{{r}_{n}}\propto n\]
C.	\[{{K}_{n}}\propto \frac{1}{n},{{r}_{n}}\propto {{n}^{2}}\]
D.	\[{{K}_{n}}\propto \frac{1}{{{n}^{2}}},{{r}_{n}}\propto {{n}^{2}}\]
Answer» B. \[{{K}_{n}}\propto \frac{1}{n},{{r}_{n}}\propto n\]
