According to Bohr's atomic theory, which of the following is correct ?

Options

A. Potential energy of electron `alpha(Z^(2))/(n^(2))`
B. The product of velocity of electron and principle quantum number `(n) alpha Z^(2)`
C. Frequency of revolution of electron in an orbti `alpha(Z^(2))/(n^(3))`
D. Coulombic force of attraction on the electron `alpha (Z^(2))/(n^(2))`

Answer

C

Explanation

`PE_(n,z) prop (-z^(2))/(n^(2)), V prop (z)/(n)`
`f_(n,z) prop (z^(2))/(n6(3)), F prop (1)/(r_(n,z)^(2)), r_(n,z) prop (n^(2))/(z) :. F prop (z^(2))/(n^(4))`
