Which of the following statements about the Bohr model of the hydrogen atom is false ?

Options

A. Acceleration of electron in n=2 orbit is less than that in n=1 orbit
B. Angular momentum of electron in n=2 orbit is more than that in n=1 orbit
C. Kinetic energy of electron in n=2 orbit is less than that in n=1 orbit
D. Potential energy of electron in n =2 orbit is less than that in n=1 orbit

Answer

D

Explanation

`a=(v^(2))/(r ), v prop (1)/(v) , v prop (1)/(n), r prop n^(2)`
`a prop (1)/(n^(4))`, (1) is O.K.
`L_(n)=(nh)/(2pi)`, (2) is O.K.
`K_(n) prop (1)/(n^(2))`, (3) is O.K.
`U_(n) prop -(1)/(n^(2))`, (4) is wrong
