The electron of hydrogen atom is considered to be revolving around the proton in circular orbit of radius `(h^(2))/(me^(2))` with velocity `(e^(2))/(h)`, where `h=(h)/(2pi)`. The curret I is

Options

A. `(4pi^(2)me^(2))/(h^(2))`
B. `(4pi^(2)me^(2))/(h^(3))`
C. `(4pi^(2)m^(2)e^(2))/(h^(3))`
D. `(4pi^(2)me^(5))/(h^(3))`

Answer

D

Explanation

`I=(e)/(t)=(e)/((2pir)/(v))=(ev)/(2pir)`
