Bohr Model: Orbits, Speed & Angular Momentum

The force acting on the electron in hydrogen atom (Bohr's theory) is related to the principal quantum number n as

Show answer and solution

Answer: (b)

$F = \frac{ke^2}{r^2}$ with $r \propto n^2$ .
$F \propto \frac{1}{n^4} = n^{-4}$
So the answer is (b) $n^{-4}$ .
