Problem

In the Bohr model of hydrogen, allowed orbits satisfy

2\pi r = n\lambda

, where

n

is a positive integer. Using this condition together with Newtonian circular motion under Coulomb attraction, what is the ratio of the electron’s kinetic energy in the

n=2

orbit to that in the

n=1

orbit? (a)

1

(b)

\tfrac{1}{4}

(c)

\tfrac{1}{2}

(d)

4
