Explanation:
.vr=nh/2pi=2h/pi
n/2=2
n=4
r (nth orbit)=0.532n^2/z A°
=0.532×16 A°
=8.464A°●[APPROXIMATELY]●~~~~~~~~~~

Option D is the right answer. angular momentum of an electron revolving in Bohr's orbit is 2h/pi, and the radius of this Bohr's orbit is 8.464 angstrom.
Given:
angular momentum of an electron revolving in Bohr's orbit = 2h/pi
Find:
The radius of the Bohr's orbit.
Solution:
we know, the equation for the angular momentum of Bohr's orbit is =
=
So n = 4
Equation for Bohr's orbit
R = 0.537n²
= 0.537*16
≈ 8.464 angtrom
∴ The radius of the Bohr orbit is 8.464 A⁰
