PhysicsSingle correct+4 / -1Question 17 of 90

Using Bohr model of quantization of angular momentum the relation between the radius 'r' of the n $^{th}$ allowed orbit of quantum number 'n' for an electron in hydrogen atom is:

r\propto n^{1/2}

r\propto n^2

r\propto\left(\dfrac1n\right)^2

r\propto\left(\dfrac1n\right)^{1/2}

Answer and worked solution

Official answer: B

Bohr radius $r_n=\dfrac{n^2h^2\epsilon_0}{\pi me^2}\propto n^2$ .

(B)

Topics:Bohr model and hydrogen spectrum
