If number of revoltutions by an electron per second is `'n_(rev)'&T` is time period of same electron in `n^(th)` shell of H-like species then correct option is :-

Options

A. `n_(rev)prop(Z^(2))/(n^(3))`
B. `n_(rev)=(1)/(T)`
C. `Tprop(n^(3))/(Z^(2))`
D. All of these

Explanation

`n_(rev)=(1)/(T) = (v_(n))/(2pir_(n)) prop ((Z)/(n))/((n^(2))/(Z)) " "therefore" "[D]`
