In the Bohr's model, let $r =$ radius of orbit, $v =$ orbital velocity of electron and $E =$ total energy. Then which quantity from the following is linearly proportional to the principal quantum number?

Options:

Answer:

Solution:

$r \propto n^{2}, v \propto 1/ n, E \propto - 1/ n^{2}$ . So $v / E \propto n$ ; while $E r \propto$ constant and $r / E \propto n^{4}$ .
