Q. What is the velocity of electron present in first Bohr orbit of hydrogen atom?
Structure of Atom
A
$2.18 \times 10^5 \,m/s$
5%
B
$2.18 \times 10^6 \,m/s$
72%
C
$2.18 \times 10^{-18} \,m/s$
17%
D
$2.18 \times 10^{-9} \,m/s$
6%
Solution:
From Bohr’s theory, $v=2.18\times10^{6}\times\frac{Z}{n}\,m/s$
$=2.1\times10^{6}\times\frac{1}{1}$
$=2.18\times10^{6}\,m/s$
