In Bohr model of hydrogen atom, the force on the electron depends on the principle quantum number as
$F \propto 1/{n^3}$
$F \propto 1/{n^4}$
$F \propto 1/{n^5}$
Does not depend on $n$
The ratio between total acceleration of the electron in singly ionized helium atom and hydrogen atom (both in ground state) is
When the accelerating voltage applied on the electrons increased beyond a critical value
In Rutherford's experiment, number of particles scattered at $90^{\circ}$ angle are $x$ per second. Number particles scattered per second at angle $60^{\circ}$ is
What is shown by Thomson's experiments of electric discharge through gases ? And explain the plum pudding model.
In Rutherford scattering experiment, what will be the correct angle for $\alpha $ scattering for an impact parameter $b = 0$.....$^o$
