Bohr Model: Orbits, Speed & Angular Momentum

Consider an electron in the $n$ th orbit of a hydrogen atom in the Bohr model. The circumference of the orbit can be expressed in terms of de Broglie wavelength $\lambda$ of that electron as

Show answer and solution

Answer: (d)

$mvr = \frac{nh}{2\pi}$ and $\lambda = \frac{h}{mv}$ give $2\pi r = \frac{nh}{mv} = n\lambda$ .
So the answer is (d) $n\lambda$ .
