Which of the following relation is incorrect regarding Bohr's theory ?

Options

A. Velocity of electron `prop 1/n`
B. Frequency of revolution `prop1/n^(2)`
C. Radius of orbit `prop n^(2)//Z`
D. Force on electron `prop 1/n^(4)`

Answer

C

Explanation

Radius of orbit is directly proportional to ratio of square of principal quantum number and atomic number
i.e. Radius of orbit `alpha n^(2)/Z`
For H-atom `r_(n)=(n^(2)xx0.529xx10^(-8))/Z` cm
