उत्तर

The angular momentum of an electron revolving around the nucleus in a hydrogen atom is quantised and given by

`L = (nh)/(2pi)` For n = 2

`L = (2h)/(2pi) = h/pi = (6.6 xx 10^-34)/3.14`

= `2.10 xx 10^34` kg m2s-1

Obtain an expression for the radius of Bohr orbit for H-atom.


The gravitational attraction between electron and proton in a hydrogen atom is weaker than the Coulomb attraction by a factor of about 10−40. An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction. You will find the answer interesting.
