According to Bohr.s atomic theory, which of the following relation (s) is (are) correct ?

Options

A. Kinetic energy of electron `prop (Z^2)/(n^2)`
B. The product of velocity of electron and the principal quantum number `prop Z^2`
C. Frequency of revolution of the electron in an orbit `prop (Z^2)/(n^3)`
D. Coulombic force of attraction on the electron `prop (Z^3)/(n^4)`

Answer

A, C, D

Explanation

`*` Kinetic energy of electron `prop (Z^2)/(n^3)`
`*` Frequency of revolution of the electron in an orbit `prop (Z^2)/(n^3)`
Coulombic force of attraction on the electron `prop (Z^3)/(n^4)`
