Question

An electron charge e mass m and a positron charge e mass m revolve around their common center of mass under the influence of their attractive coulomb force Find the speed v of each particle in terms of e m k and their separation L

Answer 1

Answer: v = 2π2 Kme2 Z / nh

Explanation:

The formula for velocity of an electron in the nth orbit is given as,

v = 2π2 Kme2 Z / nh

v = velocity

K = 1/(4πε0)

m= mass of an electron

e = Charge on an electron

Z= atomic number

h= Planck’s constant

n is a positive integer.
