Question

IN hydrogen atom ,an electron is revolving with angular frequency 6.28rad/sec around the nucleus .then the equivalent electron current is_*10 to the power -19

Answer 1

Answer:

Electric current, $1.59\times 10^{-19}\ A$

Explanation:

It is given that, an electron is revolving with angular frequency 6.28 rad/sec. We know that electric current is given by the ration of electric charge per unit time. Mathematically, it is written as :

$I=\dfrac{q}{T}$

Angular frequency is given by :

$\omega=\dfrac{2\pi}{T}$

$T=\dfrac{2\pi}{\omega}$

$T=\dfrac{2\pi}{6.28}$

$T=1.0005\ s$

Electric current, $I=\dfrac{e}{1.005}$

$I=\dfrac{1.6\times 10^{-19}}{1.0005}$

$I=1.59\times 10^{-19}\ A$

$I=1.6\times 10^{-19}\ A$

Hence, this is the required solution.
