Ratio of centripetal acceleration for an electron revolving in $3^{rd}$ orbit to $5^{th}$ Bohr orbit of hydrogen atom is

Options:

Answer:

Solution:

Centripetal acceleration $a = \frac{v ^{2}}{r}$ $v \propto \frac{1}{n}$ and $r α n^{2}$ $∴ a = \frac{1}{n ^{4}}$ $∴ \frac{a _{5}}{a _{3}} = \frac{( 3 ) ^{4}}{( 5 ) ^{4}} = \frac{81}{125}$
