Bohr Model: Orbits, Speed & Angular Momentum

The de-Broglie wavelength of an electron moving in the $n^{th}$ Bohr orbit of radius 'r' is

Show answer and solution

Answer: (c)

Bohr condition: $2\pi r = n\lambda$ (whole number of de Broglie waves on the orbit).
$\lambda = \frac{2\pi r}{n}$
So the answer is (c) $\frac{2\pi r}{n}$ .
