Question

Suppose an electron is attracted towards the origin by a force$\frac{k}{r}$ where ${\rm{'k'}}$ is a constant and ${\rm{'r'}}$ is the distance of the electron from the origin. By applying Bohr model to this system, the radius of the ${{\rm{n}}^{{\rm{th}}}}$ orbital of the electron is found to be ${\rm{'}}{{\rm{r}}_{\rm{n}}}^\prime $ and the kinetic energy of the electron to be ${\rm{'}}{{\rm{T}}_{\rm{n}}}^\prime $. Then which of the following is true

Accepted Answer

${{\rm{T}}_{\rm{n}}}$ independent of ${\rm{n}},{{\rm{r}}_{\rm{n}}} \propto {\rm{n}}$

Answer

${{\rm{T}}_{\rm{n}}} \propto \frac{1}{n},{{\rm{r}}_{\rm{n}}} \propto {\rm{n}}$

Answer

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

Answer

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