In Bohr model of hydrogen atom, the force on the electron depends on the principal quantum number as
$F \propto 1/{n^3}$
$F \propto 1/{n^4}$
$F \propto 1/{n^5}$
Does not depend on $n$
Explain the formulas of energy of electron in atom revolving around the nucleus in different orbits.
Which one did Rutherford consider to be supported by the results of experiments in which $\alpha - $ particles were scattered by gold foil?
In gold foil experiment number of deflected $\alpha -$ particles at angle $90^o$ is $63$ than number of $\alpha -$ particle deflected at $120^o$ is
$\alpha - $ particles of energy $400\, KeV$ are bombarded on nucleus of $_{82}Pb$. In scattering of $\alpha - $ particles, its minimum distance from nucleus will be
Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. (Hydrogen is a solid at temperatures below $14\; K$.) What results do you expect?
