According to Bohr's theory of hydrogen atom , for the electron in the nth premissible orbit

Options

A. the linear momentum is propotional to `(1//n)`
B. the radius is propotional to `(n)`
C. the kinetic energy is propotional to `(1//n^(2))`
D. the angular momentum is propotional to `(n)`

Answer

A, C, D

Explanation

`P_(n) = mv_(n) , P_(n) = v_(n) prop (1)/(n), r_(n) prop n^(2) and K_(n) = (K e^(2))/(2 r_(n))`
i.e., `K_(n) prop (1)/(n^(2)) and L prop n`
